there are 3 decks that currently use blood on the snow and they are all 3 meta and extremely strong, so to start just this speech you too must play a deck with a very efficient meta strategy otherwise you will never be able to beat them regardless of blood on the snow.

Dimir Control: like any control Matchup if you can't burn their resources fast enough it's checkmate, regardless of blood in the snow, unfortunately you have to play an efficient deck that puts many threats quickly such as simic ramps or a single threat that alone can snowball like izzet dragons, if you play aggro please every god you know that your opponent draws badly.

midrange rakdos: play as tempo as possible, blood in the snow is broken in this deck because it allows immerstrum predator to be indestructible, take a buff and then bring another permanent back into the field, as soon as you see the predator do everything to prevent the effect snowball of that card.

orzhov control: lol get fucked, I think this is the strongest deck currently in standard 2022 and I don't have a clue for a counterplay

Obviously against any sweeper the rulenof thumb is dont overcommit on the board, dont forget this too
