Pay 800 Life Points and select up to 2 of your removed from play Psychic-Type monsters
Decks from any format (e.g., Standard, Expanded, etc.) can be played, but note that success in the game is based on overall damage output, so you may deal more damage, and thus have more success with newer cards (i.e., Sword and Shield onwards)
Just be mindful that if your opponent can respond mid-loop with a removal or bounce spell, you could end up losing your entire board
Many of these cards revert to the small font to fit the rules text in the allotted space
I think its a potentially great card in a shell like Osgir in particular
Double attack and trap resistance are more useful if you stay on the field, so it's a shame that it can only stay for 2 turns at present
