Brago, ETB Eternal (EDH / Commander)

Do you like 'enter the battlefield' effects? Do you wish they could occur more than once? How about triggering the effects every turn? Then Brago, King Eternal may be for you.

Basic interactions in the deck:
The main goal of the deck is to bounce as many permanents as you can, generating all of the value.
When a permanent is bounced, it usually enters play untapped. This can be used to get two uses out of mana rocks and give your creatures pseudo-vigilance, along with the ETB ability.
Panharmonicon and Altar of the Brood are in the deck to gain extra value from permanents entering play.
Manifested cards, when bounced, enter the battlefield face-up. This means that any permanent manifest can be "cast" by bouncing the card. However, this does NOT apply to instant or sorceries, those cards are flipped face-up and put straight into the graveyard.
Brago needs you to get in with combat damage, so blockers will need to be removed. Diversionary Tactics and Opposition are used to tap down flying blockers to allow Brago through. Aboshan, Cephalid Emperor and Dream Tides are used to tap and lock ground blockers to allow for you to survive creature-based strategies.

More roundabout interactions:
A new "combo" added to the deck revolves around Smothering Tithe and group-hug draw spells. There are 5 this deck is running: Fascination, Minds Aglow, Prosperity, Skyscribing, and Windfall. When any of these cards are played with Smothering Tithe in play, you create a treasure for each card drawn by each opponent. These treasures can then be used to fuel your next draw spell. The magical Christmas land interaction is this "combo" with Altar of the Brood in play.
