These cards I am really excited for. My creative senses are tingling!
I'm excited for Sram, Senior Edificer, not only for its abilities but because it hints to equipment being useable. Which is great because it means that my
Weapons Trainer and
Stone Haven Outfitter won't be wasted before I have had a chance to put them in a deck.
But really! An extra draw for casting any vehicle, aura or equipment? Think about a zero drop
Bone Saw, or
Cathar's Shield. The synergy in this set is amazing.
Sram's Expertise is another interesting card 4 mana for two very potent effects. (3 servo tokens and a 3 mana, free cast) You could potentially have 5 tokens with
Servo Exhibition as your 3 mana or less card and then activate
Westvale Abbey. Either that or you can use it in a variety of other ways that will make Selesnya tokens playable, especially with
Oath of Ajani,
Nissa, Voice of Zendikar still Standard legal.
Gonti's Aether Heart is very easy to cast with the amount of cards that lower the costs of colourless spells and the amount of energy generation that is in Kaladesh. I don't think it is as great as
Mindslaver but I am trying to think of how I can abuse it with the Eldrazi's return a permanent from
exile to the graveyard. Extra turns are always nice.
Addendum: I've seen
Peacekeeper Colossus, as well as Consulate Dreadnaught and I can see some amazing synergy there. You don't need to crew Consulate Dreadnaught, just activate
Peacekeeper Colossus 's ability (1W) and Crew 6 for basically nothing, allowing you potentially play Consulate Dreadnaught (7/11) on turn 4/5
