Better to take whites usual supply of Flying, Lifelink and First Strike creature and make them bigger and better with the second ability
With that said, we can't ignore the few monsters who weren't big enough to make the cut, because any of them could be a strong option for your Commander deck
Playing Lotus Cobra on turn 2 will give you enough ramp ammunition to cast 4- or 5-drops the next turn with ease, and it scales very well with ramp effects that put lands into play
They'll only create Blue or Green, and that mana can only be used to cast creature spells, but that's still very strong
:)...And no, it's not "If your opponent would search/draw extra, instead gain 1 life." :) We can give white rewards that are awesome - just searching your opponent's library and then stealing their cards is not a white thing to do, in game or philosophically.And finally, many thanks again to @SixthComma for all his hard work on white
