Rarely do you see impulse draw at this magnitude
Shiko and Narset, Unified One generic, one blue, one red, one white legendary creature - Human Spirit Dragon - 4/4 - Mythic Rare Flying, vigilance Flurry - Whenever you cast your second spell each turn, copy that spell if it targets a permanent or player, and you may choose new targets for the copy
When you write out your sideboard plans with Humans before a major tournament, I suggest including the default Meddling Mage selection for each major matchup
If you play some extra colors and cool, splashy cards alongside those lands, thats even better
Or you can have combos with Aetherflux Reservoir and Mystic Forge, which allow you to draw and play a bunch of cards, and repeat the process until the Reservoir kills everyone
Ultimately, Pantlazas astounding triggered ability is simply too much card advantage to ignore, hence why it tops the list
