Domino, Luck Incarnate

Probability Manipulation — If you would roll a
die, instead roll that many dice plus one and
ignore one of those results.
{w}{w}: Roll a six sided die. The next time Domino
would take damage, prevent X of that damage
where X is equal to the result.
{r}{r},{t}: Roll a six sided die. Domino deals
damage to target creature equal to the
result.
