You still need four mana to play Living End so Dark Ritual could help you play it faster. Also, with all the cycling you have lots of ability to put creatures in your graveyard but you still need to wait for Living End to come into play; Rift Elemental - Timecrafting could speed that up. Entomb works as a tutor for you. Bojuka Bog before Living end comes into play could be devastating.

Dark Ritual and Entomb are not modern legal.and you cast Living End by the cascade trigger from Violent Outburst or Demonic Dread. so all you need to do is fill your yard with the cycle creatures.and almost nobody plays Bojuka Bog. the only graveyard hate I'm afraid of is Rest in Peace

I enjoy running Architects of Will instead of Avalanche Riders, the extra cycling and topdeck manipulation can help in the late game and it will also speed up your deck a little.

thanks, i'll try it out then :)

Fulminator Mage is definitely expensive, but Avalanche Riders is cheap and playable.

Architects of Will is not my favourite cycler at all at the moment.
