Have fun locking your opponent out of their turns while beating down their life total with your growing horde of indestructible creatures.

Use Glorious End to counter your opponent's spells or even lock them out of their turn on their upkeep (they don't even get to drop land if you end the turn on their upkeep). Use Angel's Grace to stay in the game or Sundial of the Infinite to end your turn and exile the "lose the game trigger". Use Chance for Glory to go again and use your defenses against "lose the game trigger" (Sundial of the Infinite, Angel's Grace, or even Glorious End).

Use Monastery Mentor to make tokens with prowess while boosting your Dreadhorde Arcanist with Brute Force, Built to Smash, or the Integrity side of Integrity / Intervention. Use Feather, the Redeemed to return those spells to your hand (you control the order triggers resolve at end of your turn so you can get these cards back to your hand, manually end the turn then exile the "Lose the game triggers", or just let them resolve after an Angel's Feather. Don't forget, Chance for Glory makes your creatures indestructible indefinitely and gives you another turn after this one.

Use Dreadhorde Arcanist to recast Chance for Glory or your Faithless Looting to search for another turn or a way to end your opponent's turn. It can also be used to cast the Intervention half of Integrity/Intervention for a little life gain.

I'm crap with designing land bases so that probably needs work, but I hope you have fun breaking this idea over your opponent's head.
