Playing against previous deck types

dear hs,

would be great if you introduce a new set, that people should play the new set not mech mage from a year ago with no new cards, you wanna be elligble to play the new standard

introduce that requirment you did with theorycrafting stream. you need at least 5 nathria cards to play the new standard or else go play wild

you have wild for a reason you have standard for a reason i never got how this isnt a thing yet, you basically get players to play the new set, and you dont keep previous decktypes around

how is this not balancing 101
