MORE! Comming Soon

Ephemeral Bomb's effect technically makes it automatically kill itself when you use its effect and creates an infinite damage opportunity, since it would be the End Phase of that turn. Just like how you can infinite reborn a Treeborn that's destroyed by the effect of your opponent's Oppression.

Ephemeral Fury basically just Normal Summons itself without a tribute and then gets destroyed. Kinda pointless.

Good Point...I miss one thing is Bomb's effect and is that can only be sumonned once.

Fury, looks bad now but with further support he is very important to the archetype

A few cards added

[Zeppeli Gyro Supreme]

Ephemeral Head Hunter seems overpowered. A lot of decks would be able to abuse it.

And by the way, the Fusion Synchros are a bit overpowered. Way too easy to Summon in my opinion.

Fixed them a bit
