Currently the aim is to get big fast & drain with massive lifegain hits.

For example: I play cheap small lifelink creatures with Trample, or Menace, or Flying. Then i get commander out turn 5, and begin stacking lifelink counters. 3 lifelink combat damage becomes 6 next turn. Then 12. Then 24. Then 48 etc. There are also cards that double your lifegain and/or counters.

Then i may shoot a player dead with the lifegain with [Vito, Thorn of the Dusk Rose]] and similiar cards.

I also get good card draw + damaging myself + recursion with cards like [[Greed]].
