Couldn't cast "Reject" instant spell
I wasn't able to cast instant spell "Reject" twice during my opponent's turn, although I had mana for it.
The card wasn't even highlighted, very strange.
I have 5 untapped snow lands and untapped sculptor of winter
I cast old growth troll
Opponent casts reject... game asks if this spell resolves, i click resolve
Instead of asking me to pay 3, my spell just gets countered.
The game does not check to see how many mana can actually be used; it just checks number of tapped and untapped lands.
Please fix this!!
