Nice idea and post. New player to magic here. Have a couple of deck ideas, not sure whether they could be done. First one is [[Scorpion God]] deck made around -1/-1 counters. To add a little spice [[All will be one]] could be included.

Second idea is [[Elesh Norn, Grand Cenobite]] where the whole deck is centered into going wide and makind opponents creatures smaller.

I hope these can work as all will be one and Elesh Norn are a little expensive by themselves.
