"Warrior Dai Grepher" + "Spirit Ryu"A Fusion Summon of this monster can only be conducted with the above Fusion Material Monsters. As long as this card remains face-up on the field, negate the effect of a Normal Trap Card by paying 1000 Life Points. Negate the effects of a Spell Card that targets this card and destroy it.
Sad, I thought I could use fusion substitute for this card.
Not sure if bug, interaction I don't know about, or my duel settings are messed up, but I just had a duel wherein I was at 900 life, Tea's "Pay 0 life" ability was activated, this guy was on the field, and the game did not let me counter a Michizure that targeted him. It cost me the game and confused the hell out of me.
