Tainted Pact Unsable in the Current Cilent
Currently Tainted Pact is card that is almost unusable on MTG Arena. When you exile a card with Tainted Pact a 2 second animation plays exiling the top card of your library and this counts towards your timer. This animation makes it impossible to resolve Tainted pact on your turn in your library has 45 cards or more. If your timer runs out the Arena client will auto resolve Tainted Pact and exile your entire deck. Your timer is even less on your opponents turn so If you attempt to resolve Tainted Pact on your opponents turn you can only do so if you have less then 25 cards in deck. The Tainted Pact issue on your turn could be solved if the animation doesn't play or they give you an extra 20 seconds to resolve Tainted Pact. The issue on the opponents turn would require even more time added but the card itself Tainted Pact is a instant which is absurd you can't use it as an instant.
