The Mistform Wall Dilemma: Mistform!
In Blue/Red, it is simply the best card; in Blue/Black there is nothing that really fills its slot, and in Blue/Green or Blue/White you aren’t likely to win anyway. Mistform Wall is truly one of a kind in Onslaught, and therefore should be picked as highly as possible. You will find replacements for Ascending Aven in both Blue archetypes – not so for Mistform Wall.
