Survival Elves is a creature-based mana ramp deck using Survival of the Fittest and Gaea's Cradle to flood the board and overwhelm you, with no graveyard dependency to punish, so the extra Tormod's Crypt is mainly a cheap, free inclusion rather than a dedicated answer. Arcane Denial is a weak card here because it trades one-for-one at best and gives them a card that fuels their already explosive mana engine, while you'd rather spend your mana assembling your own kill. This matchup comes down to racing their board development with your combo speed, since they have very little direct interaction to stop Brain Freeze or Ill-Gotten Gains. Keep your ritual and combo package fully intact.
