You use the card, and its effect triggers at the end of the turn. So you use it, then attack and 🔥 your own monster, then it activates. Not very useful.
@anoymous activate this card, attack a card w a higher attack than warm worm, this card is destroyed then sent back to your hand... so u can use it again...
I tried to use it in MP2 and it won't let you... So before I doomed myself with that play, how was I supposed to know it's MP1 only? It doesn't say on card... Anyone?
