King of Hearts

Other creatures you control with the word
"Gambler" in their text get +1/+1.
Gambler- At the beginning of your upkeep, you
may reveal the top card of your library. If it's a
non-land card, you may put a +1/+1 counter on
up to all creatures you control. If it's a land card,
put 2 -1/-1 counters on King of Hearts.
Whenever a Gambler ability you control activates
and a land card is revealed, you may treat it as
though King of Hearts activated that
ability.
