(It's also an exchange that leaves the control player ahead on card advantage)
Before I start, some caveats: I will not go through the whole deck list of each deck (so, please find them here) and I will be proposing cards that are US$10 or less
Since it's so low, you can copy multiple artifact abilities in one turn without investing a ton of mana, so you can hold it for other spells and interactions
The layout is as such: 10 Commons or uncommons 2 Cards of each color 1 Multicolor, artifact, or common or uncommon land 1 Rare or mythic rare 1 Future Sight frame card There is a 60% chance for a rare or mythic rare
With Krark's Thumb in play, you have a 42.19% chance of drawing 9 cards and untapping all your lands
