TL;DR - "Fair" deck wants to cast Siege Rhino & if it dies, play it again - either with Liliana or Den Protector
Update of my "BFZ Cliff Jumping" deck, taking a different direction to approach Siege Rhino + Liliana synergy. By this, I mean playing a Siege Rhino and having the ability to flip a Liliana, activate her +2 and have enough loyalty to reanimate a Rhino if we have one in the Graveyard. This (and attacking) is the "go-to" win con.
The deck takes a lot of elements from the Megamorph decks that were more popular right before/as BFZ was released. I'm debating adding self-mill elements to the deck, since I have a Sultai/Abzan blue list that does that "better" with Sidisi. For this version, we're trying to power up with Evolutionary Leap by utilizing our Morph plays with Deathmist Raptor & our "best" sac outlet Hangarback Walker to grind out our opponents Rock-style.
Cards I'm on the fence with in the main deck:
Whisperwood Elemental - has pretty solid synergy in the deck, since every creature you flip over EOT can bring back your Raptors. Problem being if I dn't run 4 Raptors, this may not be the best. Also fights for slots with Rhino and Tasigur. He does however, help with board wipe scenarios.
Painful Truths - Card draw seems pretty solid, combined with the Evolutionary Leap digging we can find answers easier. However, 14 spells may be too many, and this may just be a sideboard card for control matches. May just become Dromoka's Command in the main deck.
Utter End - Solid removal spell, but may be more of a sideboard option. Could bring in Ob Nixilis maindeck, free up space for the other Rhino/Whisperwood, or swap places with the 2 Ultimate Price in the sideboard for lower-drop creature hate (aka Maindeck Jace answer).
Nissa, Vastwood Seer - Helps grab us a land, but we only have 2 targets in this list. Another really great way to give card advantage when flipped & can give us a threat. Her ultimate has "combo" potential with Shambling Vents - but that isn't our main game plan. Would probably become Hangarback/Raptor #4 or (less likely) Liliana #3
Cards I'm on the fence with in the Sideboard:
Sorin, Solemn Visitor - He's mainly an extra win con we can toss in against Control, or any other match that may not expecting him. Could use his slot for one of the Painful Truths, or a 2nd Ob Nixilis (which at least gives us removal in addition to card advantage)
Dragonlord Dromoka - Another solid card against Control, can also help us curve out big against other "fair/grindy" matches. May just want this extra slot for Anafenza (for Rally hate).
Cards I'm thinking of adding:
Wingmate Roc - Ways to break up other "fair/grindy" match ups via going to the air. Another way to gain life, rewards attacks that go un-blocked due to threat of Liliana flipping.
Anafenza the Foremost - Aggressive, big body for only 3 mana that works great against Rally decks. Hard to argue downsides to having a few of her.
Dromoka's Command - Lets us get a little more aggressive with our board thanks to pumping & Deathmist Raptor fights.
