For either Tanglevine or Quicksand- Can't you just Teleport out of it for zero mana as a quick action?
It seems these restraining cards should be more powerful to be playable. How are players getting usage out of these?
They are escapable like this because there is no way to counter them.. nullify doesnt stop conjurations like it does an enchantment such as enfeeble. Because there is no way to counter them they are amazingly useful. Sure he can weasle out, but youre making them spend time and effort into doing that. I get great mileage out of tanglevine and run it in almost every book I build.
Because there is no outright counter, there is the extra escape option of the teleport. If teleporting didnt get you out the ONLY possible escape would be attacking it, and in Quicksand that wouldnt even be an option.
Though honestly, Ill gladly burn one of my Tanglevines to make you burn your Teleports. Especially if you are just porting to the same zone you were already tangled in anyway.
