Mandatory tome mill deck mixed with elf plan - this deck can often win in a pinch if you can manage just enough to mill them out.
Tome of Horrors
is a ridiculous card. Get all the Tomes out you can and watch your foe melt. Steal if you have spare power.
and Sunset Stone
are both here to contribute to the elf plan. Both up the damage, and thus discards. Bloodseeker
and Impending Doom
both are the standard tome self-damangers - Bloodseeker is better here due to the elf lean, but Doom can provide good air coverage
is the other standard discard unit, and also provides important life intake.
does very good work in this relic-focused deck, and is a good candidate for receiving lifesteal.
and Elder Astrologer
both let you temporarily pass lifesteal onto other cards.
works well with all the elf buffs here and is good for getting other chunks of the plan in.
are mostly here to keep the self damaging cards from getting turned to dead weight, but can be useful elsewhere.
Tavia, Lethrai Raidleader
is good to move in if you get a lot of elves out fast, or if you need another unit fast.
Eremot, Death Incarnate
is just ridiculous for mill decks, and his effect is scary even if permafrosted.
Acantha, the Huntress
is a very niche use, but if you end up in a standoff due to one unit, she's a good fix.
