pokemon card game scarlet & violet collection file set n (Japanese) Toys & Games Scarlet & Violet Fun Pack

For the low, low cost of one card, you get to attack again, draw a card, and use all of your mana a second time, plus get a crack at additional upkeep/end step triggered abilities and all that good stuff

A copy is created even if the spell that caused Galvanic Iteration's ability to trigger has been countered by the time that ability resolves

This means you can put him down on the board to earn a lore, then quest with him next turn for another lore, before having a character like Madam Mim, Snake enter play to bounce him back to your hand, earning you yet another lore

Not only can he call in other Astartes for assistance, with them (or with other tokens) comes important intel, as he's also a master tactician

Also, watch out for chances to use this post-combat after something has been damaged to finish off threats outside of the 5/5 range
