The aim is to get Talir and Voda in play to set off a huge destiny chain. First we need at least 8 power, which we usually get with Mask. Then, get a Merchant in the void, play Talir, and Last Chance the Merchant to draw Voda with destiny. Alternatively, with 11 power you can play Talir then Merchant both from hand. Alhed will make your units huge, and you can finish off your opponent with Xenan Initiation on Talir.
Previous version: Destiny combo
You should usually redraw unless you have merchant or mask.
Its good to keep a sigil in hand so you have more undepleted powers.
Wait until your opponent isn't leaving up fast removal if you can afford to.
Play quickly on the turn you combo off.
If you are going to modify the deck, be careful not to add too many cards that don't get destiny from Talir or Voda, since it will make the combo fizzle more often. Currently, all the spells draw a card, so they don't interfere too much.
