Damselfly does one less damage but makes 1 per turn. Gnome Rider does even less, but still generates. Micro abomination and brimstone eater are UP right now.
If generating 1 per turn is worth 1atk and 2 def, it's balanced. For unupped the cost is increased by one from upped, which is similar to other ups.
All those creature generating
per turn come with much less HP (Thunderstorm and all gone), and only Gnome Rider is unuped, or Devourer if it counts.
While Gravitation Guard takes lighting or above to kill (with momentum it takes a second lighting.)
Compair with Gnome Rider, +2|+3 for that extra pillar are just crazy, the proper creature it should compair with is frog
Or with the other way to see it, even you take away the generation, just +2|+1 worth another 1
.
On the upped side, +1|+1 over a 1
creature for 0
, no-matter how UP is that creature, are just crazy.
Almost every combo micro abomination can do, it does better.
Almost every combo a 3|3 frog can do, it does overkill.
