Moving forward, please cut down the amount of non-land-permanent removal in new releases. To a certain threshold, larger board states make the game more interesting and the 90th percentile board states in Standard atm are trivial.

FWIW, there's so much cheap Black removal (much of it uncounterable) + sac health card advantage (e.g. Phyrexian Arena) atm that one can trivially brew an "all-kill" kinda' OP 1-3 mana "control" deck + Cavern of Souls (to make your 2-3 win-condition creatures un-counterable).

But more importantly, this sort of deck is very unfun and uninteractive to play with and against.

I've "committed that sin" and won't repeat it. ;)
