makes sense, since it's one of the best commanders in the set, and probably one of the best Bloomburrow cards overall
As such, these ring cards will only be playable in Commander and even have a little LTC stamp in the corner
Start from the 100-card total, subtract your single commander, then fill the 99 using the ratio above: lands first (36-38), then the ramp, draw, and removal cores (roughly 10/9/9), then 7-10 win conditions, and the rest as synergy and flex slots
Then again, combat damage isnt the most important thing for a lot of decks, so maybe not
The cards in the decks arent exclusive and can be found in Fabled packs
However, thats not the only reason his price is so high
