Temur Plate, Masters 9/8/18

This is the first time I've hit Masters in Eternal, so any comments and suggestions for this deck are welcome.

The basic gameplan here is to wear out opposing removal spells with our efficient aegis units, keep the board more or less clear with removal, and slam a plate onto an aegis unit or play an Icaria to close out the game. The threat base has a comfortably low cmc with a stellar mid and late game card advantage/removal resistant plan. Vadius is an all-star here, as an early aggressive unit to start draining opposing removal, and his ultimate to make Steelfang Chakram pairs nicely with Marley's infinite army of Aegis units. Given that this deck is still able to play a long game, activating his 7 cost ultimate is very reasonable, and dramatically boosts his power as a late game draw.

Marley herself, I have discovered, is ridiculous. The aegis(!) bodies she generates ensure plate targets. They ensure you have extra cards in hand to strategize or merchant away. They provide endless ground blockers. And, sometimes, she gets to silence something. And all while doing this, accumulating mana and tempo and card advantage the longer she goes unanswered.

EDITS:
The deck has gone through increasingly aggressive iterations, and once I got a feel for what specific lines, decks, and openings posed the most problems I was able to replace Justice's more general answers with Primal bullets and get the very appreciated bonus of Jennev merchant also being an aegis body and thus a viable late game play.

I also retooled the power base significantly. I haven't done the math on it, but adopting a fast manabase with petition and seek power to fetch (usually untapped) color pairs has greatly helped the deck take and maintain tempo.
