[2020] On mobile, it's way too easy to play the wrong card by accident (especially with lots of cards in hand)

Playing the wrong card by mistake on mobile is way too easy, and incredibly frustrating!

On mobile, your hand is in the lower right, and to play a card you need to drag it diagonally left onto the field. But if during that drag, your finger slips onto another card in your hand, you can grab the wrong spell and play it without having any option to take it back.

(This is especially problematic with lots of cards in hand, because even a tiny slip of your finger can mean you end up grabbing the wrong card. You can guard against this by pulling the card directly up and then left, or by holding onto the card to inspect that you're playing the correct card, but both those options slow the game and hurt the gameplay flow.)

I almost lost a game just now - they targeted my Abyssal Eye with a Devourer of the Depths, and I wanted to play Salvage to go Deep and fizzle their Obliterate. But instead, my finger slipped and I played Pilfered Goods, at which point I didn't have enough mana left for my Salvage, and the game ended up going on for another 10 minutes when it should have been basically over.

Suggestion: When you select a card by dragging to it from another card (rather than selecting it via clicking it directly,) the game could apply a minimum dwell time where you have to hover on the card in-hand for X milliseconds before being able to play it. That would eliminate these (super-frustrating) situations where you play the wrong card by drag-selecting it.
