Goblin Gladiator

Gambler- At the beginning of your upkeep, you
may reveal the top card of your library. If it's a
non-land card, Goblin Gladiator gets +3/+2
until end of turn. If it's a land card, it gets -3/-2
until end of turn.
"I'm not the type of gambler you expect. I gamble
with my life. Well, I guess that's no much different to
goblins who spend all their lives sitting on their butts
and rotting themselves to death trying to hit the
jackpot."
