Mischievous Ghouls

At the beginning of your upkeep, put a ghoul counter on Mischievous Ghouls then create X 0/1 Plate Tokens with Flying where X is the number of ghoul counters on Mischievous Ghouls.

{3}{w}{w}: Put a +1/+1 counter on each Plate Token
you control. Target player cannot block tokens you control this turn.

A lot of hassle for a few happy haunts.
