Like discussed earlier in the thread, I've been having some terrible luck with my Ad Nauseam flips. I'll be at 16-18 life, cast Ad Nauseam and not be able to win due to life loss, so I cut one Ad Nuaseam and added Ill-Gotten Gains mainboard again.
Also, I feel like Vexing Shusher should be mentioned. He really is the MVP against the Counterbalance match up. Not to mention he's actually got synergy with Lion's Eye Diamond, unlike the blasts. Although he does require a land increase, I really don't think you can play 10-11 land and play Shusher effectively.
If you are having trouble with your manabase this is THE BEST 5 color manabase for TES I have ever tested:
4x City of Brass
3x Bloodstained Mire
3x Polluted Delta
1x Scrubland
1x Bayou
1x Volcanic Island
1x Underground Sea

"Why the fuck'd you do that??"
