Please make an adjustment to the heist mechanic or to the heist cards. The cards are not fun to play against, and they have been making for a miserable experience in alchemy.

From a gameplay enjoyment perspective, it is not fun having your opponent consistently take the best cards out of your deck. It greatly reduces deckbuilding choices and creates imbalanced gameplay patterns.

From a mechanic standpoint:

1. Heist nonrandomly removes the strongest cards from your deck. This is problematic because it makes your own draws significantly weaker. Normally, that would have an opportunity cost for the player removing those cards like in the case of 'the stone brain'. However, the heist player instead gets rewarded and they can infinitely play the card that they just took from your deck.

2. Heist cards are too efficient for the power of their effect. Since they were printed, the heist cards have defined the alchemy format. Having a heist effect on a 1 mana modal instant is far too strong and the metagames shows it.

3. Heist is not random enough. The mechanic shows three nonland cards. Unfortunately, this is not random enough to ensure that the heist player can reasonable miss as taking a card that they want out of your deck. This creates situations where side boarding against heist becomes impossible. Putting one or two of a card in your deck against heist is foolish, because the heist deck can take that card almost guaranteed before you draw it.

4. Post-rotation, there are not enough cards that effectively counter heist. There are very few cards that can interact with the cards they take from your deck, which again, limits deckbuilding choices.

Finally, from the perspective of the Alchemy format as a whole... this format is supposed to be the format where rebalances are easy to implement. The whole point of the format is that changes can be made to problematic individual cards or mechanics. I know for a fact that there are players who have quit the format specifically because they hate the heist mechanic.

Please rebalance heist or the heist cards.
