Magic Legends card list & price guide
You'll put a +1/+1 counter on the creature with evolve
Kain is a good early play that can guarantee you the top-ups you need, and you can do some dastardly things with him, like building him tall and strapping a Vampiric Link to him to ensure you gain life off of anyone attacking with him
Pristine Alpha cards are nearly impossible to come by, as most early MTG cards were heavily played
Im very strict when it comes to giving more than one point though, as I wouldnt recommend only 5 cards for card draw, even if they are exceptional, due to the fact that you must keep the chances of having access to them high and avoid to depend on only a few cards because you can be a victim of a removal spell
And they see each other, so you get two counters for 2 mana
