Ishai, Ojutai Dragonspeaker [Partner]: That's a lot of counters if you have many opponents
Replacements Draconautics Engineer is nowhere as good as Voldaran Thrillseeker for Vivi, as it lacks the direct clean finish punch that Thrillseeker gave, and the additional counter synergy it functioned with, but the Engineers pair of abilities will work with him under Agathas Cauldron to let team Vivi make a bunch of dragons and haste them
Well, since battles are double-faced cards, we need to consider three things: How good is the front side
For instance: Creatures (21) Planeswalkers (2) Lands (22) Spells (15) By contrast, Colossal Dreadmaw is worse than Carnage Tyrant in 9.44 ways and shouldnt see play in Constructed anywhere
The card wont fit, and forcing it will warp the cardstock immediately
Who / What / Where / When / Why 5W is like a lot of flexible cards in that it isnt really efficient at doing anything specifically because each mode costs one more mana than the general cost (1R is the general cost of a Shatter effect, but on What it costs 2R) aside from the Stream of Life mode on Who, which is pretty suboptimal
