Mulligan for TP and Torgov's Trading Post, Call the Ancients, Strategize with any of your stall cards, or just look for FTPP with draw. You rarely play mask on turn 4 unless you happen to go Call --> Post --> Titan. Remember you need FFTPP and have fun :)
I am ironically too broke to craft another Jennev Cargo. This has been one of my favorite decks this set to play.
Currently hovering around a 70% winrate after 50 games in the 200-300 Master ranks. Deck holds its own against aggro and just outlives control.
The ShiftstonedEternal Power Calculator is a deck-building tool that visualizes your odds of drawing enough Influence and Power based specifically on the cards found in your deck.
My opinion is cut the contraband. You top out at 4. And I think mating call and ancient is cool. But not as reliable as a relic that cranks out tokens or creates a token on play. So I would say you'd need some kind of reliable token creator, a bunch of draw to find Mask. Then a buttload of counter spells to protect. With steely resolve, Savage denial, and unseal you should be able to protect any token you equip.
I swapped the contrabands for 1x Kaleb intervention and 2x Bore to see how it goes. Display works as an unseal, and anything display doesn't hit, bore and Intervention could get rid of. Biggest problem I found was Avigraft and Citywide Ban.
Thing is, the combo is just a nice endgame, but overall your gameplan is just to keep smashing with cheap 6/6, sometimes 7/7 charge units that are protected with aegis and the occasional Torgov
Then bore will do its job. Maybe put rain of frog in the main 2-3x if you look on my profile I did a quick build if you want to try it and let me know how it goes.
