Outside of running a compliment of Counterspell's, Im inclined to go the route of cards like City of Solitude, Dosan the Falling Leaf, Teferi, Time Raveler and Teferi, Mage of Zhalfir forcing most if not all players at the table into the same tempo of game play
Tidus, Yuna's Guardian is its Bant commander, ready to proliferate and move counters left and right
This is nasty good in tons of places from Tokens to Aggro to Burn to Spellslinger
The part that gets missed often on Plate Armor is its equip cost
Nicol Bolas, the Ravager / Nicol Bolas, the Arisen I loved playing with Nicol Bolas, the Ravager while it was in Standard and still enjoy tinkering around with it in Brawl and Commander
Genie Wonderful Trickster has an interesting draw ability but at that high a cost doesnt fit in to the small-character decks hed do best in
