At the very least, Id invest in a Gravecrawler, since it so easily comes back from the graveyard and can be sacrificed to Gisa over and over
If my hand contains a Faithless Looting, I would be okay keeping a hand if it was missing one of the pieces, especially if its a reanimation spell or mana as you have a larger number of those, but I wouldnt keep it if I was missing multiple pieces as youre not digging enough to consistently hit everything you need
If you're the monarch, until end of turn, you may cast a spell from among cards exiled with Court of Locthwain without paying its mana cost
However, since it allows you to pick and choose two of them, it can turn into a solid instant to put some pressure on your opponents
You want Giada on the battlefield as soon as possible to make the most out of its effect
Thanks for the idea
