The Great Kenneth Haight

Whenever you cast a creature spell, you may pay
an additional {w}, {u}, {b}, {r}, or {g}. If you do,
create a Rune if you paid {w} this way, draw a
card then discard a card if you paid {u} this way,
return a creature card from your graveyard to
your hand if you paid {b} this way, target creature
can't block this turn if you paid {r} this way, and
that creature enters with a +1/+1 counter on it if
you paid {g} this way.
