Once upon a time, on a table cleaned very thoroughly,
I use the Judge's Familiars/Cursecatchers and/or Lightning Greaves to provide an early prevention of killspells and/or counterspells that target my Bloom Tender, the main source of mana. The Familiar also serves as a multicolored permanent to help Bloom Tender ramp, as do the Electromancers. The Harbingers are to almost guarantee I get the Tender on time, add the 4th mana needed, and fetch the Visionary for a later combo. I use the Tender, a Harbinger if needed, a bounceland, and 2 or 3 other lands to provide 9 mana to cast and entwine Tooth & Nail around turn 5 and pull out Avacyn and Platinum Angel. This prevents almost all problems, even if just for the moment. If I dont have a T&N by then, I use the Revelation to draw about 6 cards and get one then as well as regain any life I've lost up to that point. I use the Plea to first fetch Privileged Position and the Wheel. Avacyn/Platinum Angel/Privileged Position is the main combo and it's for making my side indestructible, untargetable, and unlosable.
Next, I start getting the Shusher and Dovescape out to prevent the few board spells that can get through. Once this "Mother May I" combo is applied, I use Stoneforge Mystic to fetch Sunforger, which then fetches Research/Development, which then fetches everything I need from the sideboard to start the final combo, and the Wheel allows me to continually cast it and other instants straight from the library.
I start the final combo with snagging Congregation at Dawn, Ink-Treader Nephilim, Leonin Relic-Warder, and Cloudshift from the sideboard, as it allows me to play every other card thereafter. Once Research has put those in the library, I use Sunforger to cast C@D to put the fore-mentioned creatures and Elvish Visionary (if it's not already out there) on top of the library to set up. Once those are out, things get a tad complicated...
Sunforger then casts Cloudshift on the Nephilim, which in turn targets all my creatures, and the order and results are as such: Relic-Warder exiles Dovescape for the first few cycles so that the rest of the copied Cloudshifts can resolve without me paying for them. Stoneforge Mystic to fetch Lightning Greaves so I can keep Platinum Angel on the field in case of an auto-lose reaction as well as enabling Bloom Tender to tap for mana as soon as it gets flickered (that supplies me and teammates with infinite mana). Elvish Visionary so I draw every card in my library to play with all the mana.
So I now have it set up for infinite mana and have all permanents I need from my library out on the field. But it doesn't stop there, as I need to help my teammates. So I repeat Research to get my whole sideboard out and this is how they work: Mangara and Riftsweeper can literally exile everything I wish to infinitely, but I limit it to just the bare necessities. I play Imperial Mask to give us Hexproof. I use Pestermite to infinitely untap Spectral Searchlight to give them infinite mana and to set up Gilder Bairn to double the counters on Elspeth the turn she's played. Then I trade Elspeth and a PrivPosition to each teammate via Avarice Totem and they use her final ability to get the emblem, which is then put back in my library just to be cast and traded again to the next teammate and so on. If immediate response to a threat spell is necessary, Dovescape is instantly put back onto the battlefield to stand guard again.
Once it's all said and done, me and everyone on the team have infinite mana, infinite life, infinite bird tokens, played every card out, removed all threats permanently, have any non-permanents in our graveyards reshuffled back into our libraries, can't be targeted, can't be destroyed, and can't lose. Once the combos are locked in place, there is very, very little any deck can do to get through the defense and you can spend the rest of the game letting your team play out their decks without any problems and play Mother May I with the opponents so they can still play spells (that don't put a dent in the wall of course) and everyone plays happily ever after.
The End
