isn't plat full of fast rainbows that Pestal can't handle?
It's also full of DBH, Mono-Air, Mono-Gravity and Mono-Darkness what it can handle lots of times. Stalls are beaten if they can't get a Sanc out. And in Plat you only need 2 wins in a row for the special spin.

I played just a bit with it and here are the results...
1. Mono-Air, got a SoR-Eternity out in 2nd turn, but got double-shockwaved. No more AW after that and lost.
2. Life-Light Stall. That awkward moment when I had two SoR-Eternities out to draw-lock dexterity. Dragon and Mito with eight cards left in the deck gave me an easy win, however I might have decked out with less luck.
3. Mono-Darkness, got lucky again with a 2nd turn SoR-Eternity and could slow him down a lot, however lack of damage killed me slowly.
4. Rainbow-Rush with 2nd turn-Disco. No chance, just got a 2nd-turn Eternity (AWed, but no shard).
5. Mono-Fire. 3rd-turn SoR-Eternity denied him a lot, early dragon gave me a good shot, lost by only 11 HP.
6. (~50 HP) Pestal, no idea how I managed to get that Jade Shield out, but it countered him hard. 4 damage from his Vagger were nothing. Neither Siphons (for Eternity) nor Vampires surprised me, tho. Win.
7. Poseidon-deck with Aether splash and Ulitharid. 2nd-turn SoR-Eternity could get rid of SoP-Uli for some turns, but playing 2 in the same were too much. Eternity got both BBed and loboed, luckily AI destroyed his shard when he had no creatures out. I slowly collected quanta for the already drawn Mito-Dragon-combo, what I finally brought out. It wasn't easy in front of more BBs and Ice shield, but Jade and SoGs blocked all damage and I could kill him slowly with the 3 dragons and 2 Eternities.
-> 3:4, no EMs
All in all, it's lack of damage and - as you already pointed out - draw-consistancy are major drawbacks. Lot's of plat-decks spam creatures very fast and outrun this deck easily. I don't really know how to solve that without just making it a mono-
with GotP. Maybe -1 Eternity -1 Jade Shield +1 Mitosis +1 Dragon to get that damage-combo out faster.
