cool... i predict he'll be dead weight 99.99999999% of the time.. but if you horde cards and play politically... you might be able to pull some metagame shenaningans in a group game....
the only reason this card isnt really good is because the spells have to be sucessfully cast... so you cant save your creature thats being marked for death with a bounce spell... although you can hurt one of thiers..... kind of an eye for an eye card...
but it would make you laugh like hell in a group game..
scenarios:
opponent: ill cast washout on your creature so my white weenies will kill you
you: nonono... wrath of god...
opponent: Terror your Serra
you: well... ill... cast my FREE FLING at you!! take 4...
opponent: Ill attack and cast nocturnal raid giving all my creatures +2+0..
you: interesting.... ill cast my grinning demon as an instant to block one
opp1 turn: Ill cast birds of paradise
you: FREE duress!!
opp2 turn: Ill cast a stroke for 15.. card says X is equal to zero... ill cast my free rend flesh on HIS creature
opp3: you bastard... youre dead..
opp3 turn: ill play a cosmic larva, and then ill give it hast.....
you: not so fast.... ill play seal of doom "AS AN INSTANT" and sacrifice it.. killing your beef...
another HUGE problem with this card is you have to read minds.... and well... you have to HORDE cards... which unless youre playing politically or in a group... will kill you...
i think im gonna make him a 1/2 though... cause... he cant really do much..
