one piece card game op-03 TCG Japanese - OP03 and the formidable Big Mom Pirates Marco OP03-013 - One Piece

Jaheira, Friend of the Forest turns all of your tokens into mana dorks Treasure tokens included allowing you access to large amounts of green mana, pretty much how a strong druid in Dungeons & Dragons would in a similar context

and followed up with Vadmir with two good removal cards in hand

Once a player is instructed to do this, they have the initiative until another player takes the initiative

If the target creature is an illegal target by the time Chain Assassination tries to resolve, it won't resolve and none of its effects will happen

Note: Your creature doesn't have to survive the fight to get the artifact removal, you just have to deal excess damage
