12% is big news, by the way. Izzet Phoenix’s metagame share of 12.2% in Tampa is the highest a deck reached at any Grand Prix in recent memory. I won’t judge whether or not this qualifies as oppressive, but I’d be remiss if I didn’t mention that once upon a time Splinter Twin was banned for threatening the format’s diversity.
Equally astonishing is the win rate Izzet maintained even in the face of growing numbers. Usually, a rise in popularity goes hand in wing with a drop-off in performance. Early adopters typically outperform the average player. I thought we’d seen this effect in action with Grand Prix Los Angeles, but no, that was just temporary turbulence. The win rate went back to 57% and a bit for Tampa Bay. Indeed it is higher now than it ever was before, if only by 0.02%.
As you will see, other archetypes managed to do better than Izzet Phoenix at one or two events, but nothing outperformed the deck with comparable consistency. Also, nothing could match Izzet Phoenix’s massive sample size.
Should be noted that when he says 12.2% metagame share, it is based on a sample of 57.5% of that tournament’s full field.
So IF this 12.2% is accurate, or as accurate as it can be based on the sample, then we now know that UR Phoenix:
Day 1: 12.2% (possibly more)
Day 2: 19.5%
Top 32: 31.25%
Hopefully people can now stop claiming that the deck is overrated and not that good.
