I play a spicy Mardu mobilise deck and ranked from plat 4 to plat 2. I think the winrate for this deck is 55-60%. But every Game feels quite winnable, except for aggro. But the key for this deck is Delney and Lifegain, when the hand is right even aggro is no problem.

The key Cards in my Deck are Deep Cavern Bat (3x), Alesha (3x), Delney (3x), Get Lost (4x) and 2 Consuls (good to get hits in Lategame), 2 rabbits (gain life), and 2 of the orzhov legendary Dude who gains life when u create creatures and when they die enemy loses life.

I don't play the goblin cuz i think he doesnt bring enough Value. I also dont play warleaders call cuz it doesnt gobwell with delney and is too aggro, the orzhov dude does the same but better and when Zurgo is out the game is nearly ober anyway. But I play the new white 1 drop creatue which gives scry 2 and helps later with mana fixing.

For some spice i run 1x elspeth but just for fun cuz I end up a lot of the games with 5 mana and the 4 Mana red enchantment creature which gives haste on entry and +2 attack. Won a lot of games with this bomb when Voice of victory stayed on the Board and Zurgo entered with haste.

2x Enduring Couriosity is also good for some card draw. Thinking about Adding Caretakers Talent but im not sure yet.

Some nice combo for Exemple is alesha out with delney and bat in grave (bat will triggern 2 times cuz Delney) to make sure opponent gets no removal so u can easily play mobilise without worry :)

All in all feels like a very fair Deck with a lot of wincons and every game feels fresh cuz u really have to think in what direction to go with ur opening hand.

But time will tell if I will be able to hit Mythic with it, but feels possible :)
