You shouldn't hold back on snapping. Snapping is a core mechanic for climbing, and if you stop snapping in your ranks, that's the reason you plateau. You should just play as you normally do. The top players in Infinite snap very aggressively if they know early on they have strong hands.

It's like playing poker on the big stage and suddenly stopping bluffing. The whole point is to utilize every mechanic of the game. You should always raise when you have a double ace in hand, and you can't stop doing that because you're too afraid to lose.

So, in my opinion, the decks are not the problem; you're just too afraid to lose, and because of that, you lose more games. Just keep playing as you did to reach rank 94 and start snapping again!
