I'm a huge huge fan of using control decks and this is by far my favorite one.
A lot of the flexibility comes from the different types of threats you're actively countering with this build. For example, Send an Agent is a great early board clearer, and synergizes well with the Zido's. It's a lot of different combinations, but so many of them overlap I find it's more useful to cover this breadth of possibilities. Saying that, it's vital to pinpoint a kill strike as early as possible. This deck can last until 12-15 power turns, but it is not ideal.
I've listed some of my favorite killshots below:
1. Speed Grafter + Worldbearer Behemoth or Azindel, Revealed. Both huge hits that could turn tides if not expected, and both have remarkably annoying attack trigger effects that the opponent has to confront immediately.
2. Amaran Stinger + Raniya, Never Caught + Shadowcreeper + Silverblade Menace. I cannot tell you how many times this combo has come in handy. Honestly, as long as you're making the opponent dump spells into the void, that immediate pivot with Silverblade's ability is insanely helpful.
3. Lifesteal + Nahid, the Immortal. Nothing is more mind-numbing than pumping your health (via Dizo's Office + Xenan Lifespeaker Silverblade Menace + Eremot, Mindsplitter) and then suddenly playing this f-ing unit that forces you to sacrifice a unit or take 7 damage. It's gotten way more difficult to stack given the impossibility of even getting your health up to that amount with this deck build, but Nahid is a valuable wild card regardless.
