Put your reading glasses on because there’s a whole lot of ground to cover with this one. Before anyone says “ewww equip spell” let me point out Powered Jersey would be broken/banned in a different archetype for how much it can manage to accomplish. But don’t take my word for it, this sports equipment (eh?) speaks for itself.
Equip only to a “U.A.” monster. It gains 1000 ATK and DEF, also if it battles an opponent’s monster, any battle damage it inflicts to your opponent is doubled. If the equipped monster destroys a monster by its attack: It can make a second attack during this Battle Phase. During your Standby Phase: Banish the equipped monster. If this card is sent to the Graveyard because the equipped monster returned to the hand: You can return this card to the hand.
Now let’s break this down a little bit.
Equip only to a U.A. monster prevents it from being splashable into generic earth type or warrior type decks.
The monster gains 1000/1000. Which is really good. Like I mentioned with Aliester the Eidolon Summoner’s quick effect boost – having both boosts gives you more options to work with depending on the situation.
Also when battling an opponent’s monster – double battle damage! That’s pretty awesome, you can do some terrible terrible things with that little surprise.
Then, when you’re done with their monster (presuming that you destroyed it) you can attack again!
But unfortunately, the Jersey is so strong that a player wearing it past their next standby phase will get ejected from the game (removed from play).
However if a U.A. wearing the Jersey tags out and returns to your hand, then when Jersey goes to the graveyard it will be returned to the hand as well. Crazy strong and recycles itself using the U.A.’s own signature effect. You could also Compulsory Evacuation Device your monster, or Castel, anything really that bounces. Doesn’t matter!
So that does it for what’s written on the card. Now for what isn’t written – limitations. You can equip multiples at the same time, no problem! Multiple players can wear them at same time.
Now Mighty Slugger is a great target because of his uninterruptible attacks.. But if you want to wander into OTK territory, then you want Dreadnought Dunker in this shirt.
