Protagonist Ace Monster Card By Published: Description Yu-Gi-oH
This commander is a discard payoff, and its a nice combo with Sadistic Hypnotist since you can sacrifice the elf tokens to make them discard more cards and make more elf tokens
While it doesnt have too much HP compared to several current cards, its first attack, Aero Ball, deals 20 damage for each energy card attached to both cards in play, while the second, Deep Crush, deals a set 160 damage, though Lugia cant attack the next turn
