"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.
this can actually be summoned with the earth hex sealed fusion if the hex is on the field
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.
