So this is a deck full of janky interactions that will have your opponent screaming for a judge while you play and wanting to look through your deck when you're done.Now, the deck is all about abusing two key cards, Eldrazi Displacer and Panharmonicon
Time to get into those interactions I am talking about. First off and easiest to do, cast or displace a Reflector Mage with Panharmonicon on the field, and you get to bounce two different creatures to your opponent's hand. Even simpler is casting (of displacing)
Linvala, the Preserver
when you're behind your opponent to either gain 10 life or get two 3/3 angels. Easy peasy. Now on to the weirder stuff.
If Archangel Avacyn
flips and you don't want your whole board to die, you can activate Displacer with the damage on the stack to give your whole team indestructible when she reenters.
Everyone knows that Spell Queller is great for stopping one spell. But did you know that thanks to the power of Panharmonicon, she can catch two? Here's how it works. They cast Spell1, which you catch with queller. Later in the game when you have out Spell Queller, Panharmonicon, and Eldrazi Displacer, you displace queller so the stack looks like this [Spell2, Spell1, SQ-etb. You pop SQ-etb off to get Spell1 again which triggers Panharmonicon, so the stack looks like this [Spell2, P-SQ-etp, which you pop to exile Spell2. Now, if they kill Spell Queller, they do get both of those cards back, but still, great card.
The final interaction I'm gonna go over is going to be how we get the inevitability to make our opponent scoop or cry judge. We are going to lock them out of their draw step.Here is how it works. With Eldrazi Displacer, Thought-Knot Seer, and Panharmonicon on the field, during our opponent's turn at the end of their draw step but before Main Phase 1 starts, Displace Thought-Knot Seer. They draw an extra card and you take two non lands from them.Their draw step nets them 0 cards. And if you have more mana, just do it again.
