UR pull Odds as taken from the game:

Loop 1 T1 .025% 1 card = 1/4000 T2 .050%  2 cards  = 1/1000 T3 .075%  3 cards  = 1/444 T4 .150%  4 cards  = 1/166 T5 .300%  5 cards  = 1/66

Throw out the T1 odds and assume he hit on the rest. That's 1/4,864,464,000 and that doesn't factor in that you need two separate halves to make a MTM. Now maybe you can pull multiple UR cards on a single tier...too tired to redo the math with single card pulls but it will still be astronomical odds.
