I found this for the Deck. https://playingcards.io/game/standard-deck
But am still looking for a block tower Online option

Apologies for that! playingcards.io can be used for the deck, and for simulating the tower you can roll a d20 each time you would pull a block (or 2d20 if the game suggests pulling quickly to add risk) and if a number comes up 3 times that counts as the tower falling. Thanks for letting me know about the links! I'll pop them in the game's description later tonight
