The special Unrivaled Decidueye Event is a 7-Star Tera Raid against Decidueye with a Flying Tera Type. In the second round of this event, 7-Star Raids are available from March 24th, 00:00 UTC until March 26th, 23:59 UTC.

The Unrivaled Decidueye runs a mostly Physical attacking set, dealing devastating damage with a tera-boosted Brave Bird and amazing coverage in its movepool like Spirit Shackle and Low Kick. Be careful also as once it puts up its shield it has a high chance of hitting your pokemon with two moves consecutively.

For this raid, it is smart to bring a special attacking Electric-type like Miraidon or Bellibolt. These Pokemon resists a good amount of Decidueye's moves while also dealing super-effective damage in return.

Held Item
Life Orb

Summary

Miraidon's unique typing allows it to resist Decidueye's STAB Grass and Flying-type moves. Paired with its amazing stats, it should be able to go up against Decidueye with relative ease.

Offensively, Miraidon can use Electro Drift and Parabolic Charge to deal Super Effective damage against Decidueye. Both moves benefit from STAB and Electric Terrain, making Miraidon a deadly attacker for this raid. Metal Sound and Charge both drastically improve Miraidon's damage output, so take time to set up these moves as well.

As it will play the role of special attacker, a Modest Nature would benefit Miraidon. You can also let it hold Life Orb to deal 30% increased damage with Electro Drift.

Tera Raid Strategy

Miraidon Tera Raid Turn-by-Turn Counter Strategy
Turns 1~2	Use Metal Sound to lower Decidueye's Sp. Def stat.
Turn 3	Use Charge to double Electro Drift's base power.
Turn 4	Use Electro Drift to deal Super Effective damage, and finish the Raid.

Start the battle by using Metal Sound to lower Decidueye's Sp. Def by 4 stages.

By using Charge, Electro Drift's Base Power is then increased to 200, and with Decidueye's lowered Sp. Def stat, using Electro Drift should result in a OHKO.

Since Decidueye puts up its Energy Shield, and removes debuffs at around Turn 4, or around 80% HP, speed is key, and doing the raid with AI teammates instead may yield better results.

Key Damage Calculations

Damage Dealt by Miraidon
(-4 Sp. Def) 8910 HP (Max HP x30)	Electro Drift (200 BP, Electric Terrain, Life Orb) 6,691 ~ 7,872 (75.10 ~ 88.35%)

Note: Results in OHKO thanks to damage of AI Pokemon during your initial setup

4 Turns to Beat

Following our build and the strategy above, it should take you around 4 turns to defeat the raid Pokemon. It will take 3 turns to complete your setup, and one additional turn to defeat the raid Pokemon.

Note that this is an approximate value only, and other factors, such as the raid Pokemon removing buffs or debuffs, may affect the actual outcome.

Bellibolt

Bellibolt	Tera Type			Nature
				Quiet (↑Sp.Atk, ↓Spe)
	EV Spread
	HP: 128		Sp.Atk: 252		Def 128
Ability	Moveset
Electromorphosis	・ Parabolic Charge ・ Electric Terrain ・ Reflect ・ Acid Spray
Held Item
Magnet

Summary

Bellibolt is able to counter Decidueye effectively thanks to its natural bulk, on top of its Electromorphosis, which doubles the damage of its Electric-type moves after being hit.

Offensively, Bellibolt can deal massive super-effective damage with Parabolic Charge after lowering its Special Defense with Acid Spray.

Giving it a Quiet Nature will ensure that Bellibolt attacks before Decidueye. You can also give it a Magnet to boost the power of Parabolic Charge.

This build can take on the raid alone if the set up is done correctly.

Tera Raid Strategy

Bellibolt Tera Raid Turn-by-Turn Counter Strategy
Turn 1	Use Reflect to boost your team's defense against Physical Attacks.
Turns 2~3	Use Acid Spray to lower Decidueye's Sp. Def stat.
Turn 4	Use Parabolic Charge to deal super-effective damage, and recover HP.
Turns 5~6	After Decidueye removes debuffs, use Acid Spray to lower its Sp. Def again.
Turn 7	Use Electric Terrain to boost the power of Electric-type moves.
Turns 8+	Terastallize and repeatedly use Parabolic Charge to finish the raid.

Start the battle by using Reflect, since Decidueye is mainly a Physical Attacker. From there, use Acid Spray twice to reduce Decidueye's Sp. Def stat by 4 stages, allowing you to deal decent damage with Parabolic Charge before it puts up its energy shield.

After Decidueye puts up its Energy Shield, use Acid Spray twice again to lower its Sp. Def stat by 4 stages again. After that, use Electric Terrain to boost Parabolic Charge's damage for the next 5 turns.

Once you complete your setup, Terastallize and repeatedly use Parabolic Charge until you defeat Decidueye.

Key Damage Calculations

Damage Dealt by Bellibolt
(-6 Sp. Def) 8910 HP (Max HP x30)			Parabolic Charge (130 BP, Magnet, Electric Tera) 2,536 ~ 2,984 (28.46 ~ 33.49%)
(-6 Sp. Def, with Energy Shield) 8910 HP (Max HP x30)			Parabolic Charge (130 BP, Magnet, Electric Tera) 1,776 ~ 2,089 (19.93 ~ 23.45%)

Low Kick		90 ~ 107 (21.3 ~ 25.3%) Possible 4-Hit KO		180 ~ 212 (42.6 ~ 50.2%) Possible 3-Hit KO
Air Cutter		38 ~ 45 (9 ~ 10.6%) Possible 10-Hit KO		-
Spirit Shackle		109 ~ 129 (25.8 ~ 30.5%) Possible 4-Hit KO		216 ~ 255 (55.1 ~ 60.4%) Possible 2-Hit KO

9~11 Turns to Beat

Following our build and the strategy above, it should take you around 9~11 turns to defeat the raid Pokemon. It will take around 7 turns to complete your setup, and a few more turns of dealing damage to defeat the raid Pokemon.

Note that this is an approximate value only, and other factors, such as the raid Pokemon removing buffs or debuffs earlier, may affect the actual outcome.

Iron Hands

Iron Hands	Tera Type			Nature
				Adamant (↑Atk, ↓SpA)
	EV Spread
	HP: 252		Atk: 252		Def: 4
Ability	Moveset
Quark Drive	・ Swords Dance ・ Thunder Punch ・ Rock Tomb ・ Electric Terrain
Held Item
Shell Bell

Summary

Iron Hands is able to take Decidueye head on thanks to its typing which allows it to receive neutral damage from Grass, Flying and Ghost-type moves. Iron Hands also has decent defensive stats, allowing it to safely set up Swords Dance against Decidueye. Swords Dance is used over Belly Drum, as Decidueye is able to deal neutral damage against Iron Hands with Brave Bird, Low Kick, Spirit Shackle, and Air Cutter.

Offensively, Iron Hands can deal respectable Super Effective damage with Thunder Punch. Electric Terrain allows Iron Hands to boost the damage of Thunder Punch further, while also activating Quark Drive for an additional Attack boost.

As it will play the role of physical attacker, an Adamant Nature would benefit Iron Hands. You can also let it hold a Shell Bell to recover some HP after dealing damage.

Tera Raid Strategy

Iron Hands Tera Raid Turn-by-Turn Counter Strategy
Turn 1	Use Thunder Punch to deal Super Effective damage.
Optional	Use Electric Terrain to boost Wild Charge's damage output.
Turns 2	Use Swords Dance to raise Iron Hands' Attack stat. Be sure to do this after Decidueye resets your side's stats.
Turn 3+	Use Thunder Punch to deal Super Effective damage.

Start the battle by using Thunder Punch to immediately deal damage to Decidueye. You can also opt to deal damage using Rock Tomb early on, to reduce Decidueye's speed, allowing you to Attack before it.

Ideally, having a teammate set up Electric Terrain would be best so you can focus on dealing damage with Thunder Punch, but when playing solo, you can set it up yourself to boost your damage output.

Since this build makes use of Swords Dance and Thunder Punch, the drawback is that you will not be hitting as hard as you would if you were running Belly Drum.

Key Damage Calculations

Damage Dealt by Iron Hands
8910 HP (Max HP x30)			Thunder Punch (+2 Atk, Electric Terrain) 1,224 ~ 1,440 (13.74 ~ 16.16%)
(with Energy Shield) 8910 HP (Max HP x30)			Thunder Punch (+2 Atk, Electric Terrain, Electric Tera) 1,142 ~ 1,344 (12.82 ~ 15.08%)
Damage Received by Iron Hands

Miraidon should then use Electro Drift which should result in a One-Hit KO.

By turn 3, Magnezone should now use Helping Hand to further increase the damage of Electro Drift.
