I've played a lot of Hearthstone over the past decade, and one thing that I've loved about it is Battlegrounds, to the extent where I have stopped playing the traditional meta where you have to build actual decks. Battlegrounds is somewhat similar to the draft meta in MtG and YGO where on a turn by turn basis, you get selection of cards to draft, but with a certain economic limit of cards to pull. It corrects for "buying" your way in and instead focuses ELO on ramping correctly and inflects an RTS flavor on the game. I enjoy it a lot and I kinda wonder why such a flavor on gameplay hasn't similarly taken hold of the other classic CCGs. What am I missing or misunderstanding?
