Make a killing

Heavily Killer-focussed deck.

Apart from having a lot of cards that benefit from Killer (Cirso, the Great Glutton, Worldbearer Behemoth and Lumen Reclaimer), this card has lots of options to create copies of your Killer units. use your initial Killer charge to lure your opponent into playing a vulnerable minion and then just create a copy with refreshed Killer to crush his hopes.

Also, this deck highlights a very interesting card imo: Snapping Brushstalker

This little guy serves as a wildcard, because if you give him killer and buff him with Ageless Mentor or Accelerated Evolution, then you got yourself a spell-immune minion that refreshes its Killer charges for you. Be warned though, if you play him against an aggro deck you probably just wasted 4 mana on a creature that can't even block.

Optionally, you can add Praxis Displacer or Insistent Automaton to bounce your Ageless Mentor once you have a few 4+ cost minions in hand
