Quite possibly, though once you can pull it off it doesnt really matter how big the buff is, you just repeat it inifinte times.
I do like the fact that the mask also gives hexproof, allowing it to give some protection until you can pull off the combo.

Also the green ring that adds +1/+1 counters will do the same thing. Any buff will do the trick. the permenent ones just allow for more shenanigans.
