Try to go infinite draw cards or deal damage. Cornerstone plus Wayfaring Pilgrim plus harbinger plus one other discount site plus an owl plus all minions have charge plus Lady Iseult plus a minion that sacrifices equals draw two cards so the solution to this really is you get a bad guy avatar to attack in a corner do that and then suddenly the sac outlet is not needed. There are Genesis and deathrite sites to help and also discount sites and auto kill sites to take up slots of this combination puzzle. The minions all seem bad but can go infinite in their own rites with similar ideas. The aura can offer infinite mana and lethal can offer nearly infinite kill all minions depending on which combination you need. Consider building a deck like this one instead of playing with all of only these combos
