To me it seems like unless the game has devolved into a topdecking battle, playing any minion that doesn’t have an immediate on deploy effect is 100% pointless.
The only good 7+ cost minions in this game are all abilities (Embla, meltdown, Spectral Revenant being some but not all of the prime examples). With all the removal in this game, it feels like any card that is designed to be a strong body (Excelcious, Ironcliffe Golem, Peacemaker) really just ends up serving the purpose of drawing a removal card out - even once a topdeck battle has started. Same goes for any minion which requires you to build up ANY sort of board presence.
Despite the fact that a LOT of the more recently released removal cards are damage based (which I think is a 100% smarter way to handle removal in duelyst) there is still a lot of hard removal in the game that generates disincentive to anything that focuses on board building with strong body finishers which you can’t buff cheaply into.
TLDR: I feel this game punishes board building more than it punishes out of hand lethal and board removing control decks - something I feel is really sad since they board aspect of the game is so interesting. But I also might be jaded because of how ridonkulous Vanar control and Magmar out of hand is right now. The latter of which not necessarily being OP but making for a very solitaire-styled game.
