Even if you don't go down that route, I like Merieke Ri Berit much better as Mind Control on your commander since your opponent can't just kill this and get their card back
But foils like Pernicious Deed or even, say, Crucible of Worlds from Fifth Dawn
For three mana, Azcanta, the Sunken Ruin lets you look at the top four cards of your library and put a nonland card among them into your hand
With this deck you spend a lot of time on the back foot, but you're one card away from completely turning the game around
At first glance, its stats dont seem anything special, but if an opponent wants to challenge any of your characters while Tiana is exerted, they either get -3 strength, or pay three ink to remove that penalty
