Finals: Adam Prosak vs. Sherwin Pu
After overcoming Kurt Samson on the draw in the RUG Delver mirror, Sherwin got to lead off against Stifle hand was going to be able to mana screw Adam. After all, Sherwin knew full well that a fragile manabase was one of the weaknesses of the RUG Delver deck, and a few Wastelands plus a Stifle could be just what the doctor ordered.

Nimble+Mongoose through Sherwin's Volcanic Island, presenting him with a creature none of his lands or spells would be able to touch, and it was apparent that Prosak wasn't messing around with his hand.
Sherwin had no choice but to follow through with his plan, but that only helped grow the Nimble Mongoose, and the game was over in a hurry after multiple three damage chunks.
Adam 1, Sherwin 0
This time Sherwin got on board first, leading with Nimble+Mongoose and Tarmogoyf as Prosak filtered with Ponder. They got in for a bunch of damage before Prosak found a Nimble+Mongoose and Delver of Secrets to battle back with.

Sherwin Pu is very comfortable in the RUG Delver mirror.
Nimble+Mongooses traded all over the place after Adam blocked the first with his Delver+of+Secrets and its replacement with his own, but that left the Tarmogoyf taking unchecked bites out of Adam's life total. Submerge bought Adam a turn, but when Sherwin had the Spell+Snare for Adam's own Tarmogoyf, Prosak was out of answers and we were headed for a final game.
Adam 1, Sherwin 1
Adam's Delver+of+Secrets got him on the board first, but he was stuck looking for lands after Sherwin popped two Wastelands. That made it easy for Sherwin to fry the Delver+of+Secrets with Pyroblast and sneak a Nimble+Mongoose into play, and with a bit of flop lag—to borrow a weird poker term— Sherwin's land destruction plan from game one seemed to be finally taking hold here.
Adam was forced to discard multiple cards, but the Nimble+Mongoose kept doing its thing, plucking away for a point here, a point there, and then three points at a time after Sherwin's overstocked hand had him discarding his way to threshold.
The anticlimactic end came swiftly for Adam, as there was nothing he could do against Sherwins hand full of counters, and he was quick to offer a congratulatory handshake to his friend when the reaper cam e calling.
