If all that sounds too niche, remember you can play Metamorphic Alteration on opposing creatures to make them worse, copying a 1/1 token or whatever else is lying around
For the rest of this game, your Pokmons attacks do 30 more damage to your opponents Active Pokmon (before applying Weakness and Resistance)
Hitting both artifacts and creatures is great and can really stall decks that rely on treasures
3 Some tribes may need support by other ways of design, or rather you can tailor some of them to help support archetypes in your cube (my soldiers can support generic aggro, token, heroic, and probably some other things as well)
Thats just a part of the games normal back-and-forth
Just because I dont see a particular card being played at my LGS, despite believing its actually quite good, doesnt mean it isnt played by every single player at the LGS down the road
