Quick ruling on a combo

this combo involves 2 cards:

Everlasting Torment 2(R/B)
Enchantment
Player's cannot gain life.
Damage cannot be prevented.
All damage is dealt as though as though it's source had wither.

AND

Transcendence 3WWW
Enchantment
You do not lose the game for haveing 0 or less life.
You lose the game if you have 20 or more life.
Whenever you would lose life, you gain 2 life for each 1 life lost.

Question: Is this combo banned from clan play? You cannot gain life so therefore Transcendence's third ability would never trigger. I just want to know if I have to wait for after hours to play this combo. It is not an instant win.

Transcendence is banned flat out due to the "20 life, you lose" clause. No debate there. But the first card is good to go.

thank you
