also for me, been a while
I really loved this deck and played it at a few tourneys, but in the end always got disappointed with it being 'not just good enough' to be tier 1 ...

In my testing/playstyle, the therapies were no good ... they slowed me down a lot (T1 therapy, T2 elf and mayhap therapy again if necessary) which basically looses you 2 turns ...
anyway, I was thinking of including eyeblights ending, just to be able to destroy annoying creatures (wort in the gobo matchup, some tombstalker or a jitte equiped creature, ...)
I never tested it though ... (dumped the deck before testing it (sorry to say).

I also removed the wastelands and replaced them by forests, I was being too color screwed sometimes (opening with one wasteland and no other lands sucks) whereas they didn't win me that many games that i wouldn't have won otherwise.

the inclusion of relic, is it worth it? i mean do you play 4 main? I can see their advantages, but wouldn't 2 or 3 main be enough already (maybe include a jitte as well)?

why the woodfall primus? is it against moat? would a sky swallower not be better in that case? (or some other flyer)?

I played tsunami instead of choke just to play around counterbalance better. Is choke useful against f.e. supreme blue?

anyway, i think i will recreate this deck, it is just to fun to play and hope that someday we will be able to make it a 'deck to beat' ...
