Colin, Licker of Rims

Colin gets +1/+1 for each pint of Guinness in
your graveyard.
Whenever Colin attacks, you may pay {1}{g} to
give him trample until end of turn. When Colin
dies, create a 2/2 brown Bulldog creature token
that has "Whenever this creature becomes
blocked, it gets +1/+1 until end of turn."
"There's nothing like a good rim to lick, and a
cold pint of Guinness to wash it down."
