Holy tokens

[Langku]

Why not throw in an infinite mana combo, to do this an infinite number of times?

But all the cards have to tap to activate their abilities.

{village bell ringer} or {intruder alarm} would work here

Edit: nevermind...let me find the right card. Hold on

Edit: nevermind. The card I'm thinking of doesn't exist...

Bird, it does exist. If you had a {doubling season} and a {krark clan ironworks} with your {pentavus} it becomes an infinite +1/+1 counters or infinite pentavite token or infinite colorless mana ramp.
