~150s to death.

2 Conjure Gold (1 In Hand)
2 Vampire Elder (1 In Hand).
NO OTHER CARDS
~160 Seconds.

Mountain Wolf Rush:
4 Forest
3 Mountain Wolf

-9- Card Vampire Elder Rush Deck
3 Conjure Gold (1 in Hand)
2 Vampire Elder
3 Treasure Chest (3 in Hand)
3 Magic Mushroom (1 in Hand)
3 Ancient Woodland (2 in Hand)
~71% chance of success otherwise +45seconds to success. Expected time is about 5s faster than the normal Elder Vampire Rush.
Basically drop the Chests, and magic mushroom + Conjure gold. Use that gold to convert the Ancient Woodlands into 2 card draws each (gives you 5 cards for the cost of 4. Then summon as usual. Basically this method lets you avoid the 45s delay to get the 2nd vampire (but has more plays so takes longer to click at start).
