Apparently I’m not the only one who feels like Cartouche is a dirty word.

All the Trials and the Cartouches seem pretty good. However, since white has the best Cartouche (for now) in [scryfall]Felidar Guardian[/scryfall], I’ll choose that and since removal you can reuse is very strong, I’ll go with this triplet of colors, even though I won’t use all of the options from each color. I’ll go with sets of these four:

These might very well be wrong, but my thinking here is that we want the removal and we want bodies to put the Cartouches on.

Right now this has a casual feel, but could probably be tuned to be actually competitive in at least an event here and there.

Okay, the mana is horrible…

Probably isn’t any better than Vehicles, though.
