Trick effects should NOT count from the player's time to pick cards
Trick effects such as buffs (+2 HP or +2 Damage) or any animations (zombies/plants doing bonus damage for example) should PAUSE the timer to give players the time to choose what's next. It is not my fault that the effects are taking too long.
Wait, what am I talking about exactly? isn't the time just enough for you to pick cards?
Let me tell you what happened to me several times..
I was playing as Professor Brainstorm with heavy (Draw a card) cards, tricks, Trick or Treater (gives you a treat for your first trick) and Papparazzi Zombies (those benefit from tricks, get +1 DMG +1 HP each trick you play).
So, I was having 2 Paparazzi Zombies, 1 Trick or Treater and I had Lurch for Lunch (a zombies does a bonus damage trick), so what happened was I couldn't use all my cards because the game was doing the animation + buffing 2 Paparazzi Zombies simultaneously + Trick or Treater was giving me a treat while locking the ability for me to pick cards from the deck. And then in some games, I use Fun-Dead Raiser with all that as well or other trick cards... so I end up having no time to deploy the rest, even though I pick as fast as I can.
My suggestion is that, that the timer is paused while doing all those effects.
