this card has so many different possibilities on top of being one of the cheapest plainswalkers.
my favorite use for this card was in my merfolk milling deck however i did run him in my counter deck for a while.
Strategies and game play:
the biggest strategy Ive found with him is with clockspinning or a prolif deck.
Combos with other cards:
as i mentioned above clockspinning makes a good combo as dose archmage ascension
Ways to counteract it:
the most obvious way to protect your self agents Jace is to kill him as fast as possible however don't forget about your opponent as well!!
strenghts are all printed on his card add zero counters to brainstorm every turn is probably the lest likely to draw you aggro however i have yet to meet a player who wants u to Exile there library.
the biggest disadvantage of this card is that it draws an incredible amount of aggro from your opponents
i would give this card a 8.5 out of 10
