Tibalt, Master Gambler

Hazard 2 (When this creature enters the battlefield,
roll up to 2 six-sided die. For each die that lands on a
4 or higher, put a fortune counter on it.)
As long as Tibalt, Master Gambler has a fortune
counter on it, if you would roll a die, instead roll
two of those die and ignore one of those results.
At the beginning of your end step, if Tibalt
has no fortune counters on it, sacrifice it.
