Just paying 4 mana to copy the strongest token around (populate, if you will) is very good, and lots of cards and commanders can give you a token every turn, meaning that this class will draw you a bunch of cards even on your opponents turns
Yeah, that's a strong effect
In your draw step you can draw, for free, two more cards and then place two cards you've drawn on your deck in any order, so it's like a free Sensei's Divining Top, and if you replace those draws with something like Abundance then you'll not have anything to put back so you get all three effects
With Theros being built around enchantment themes, being able to combat those is some way is likely to be relevant for the Dimir decks out there
This card, if not for the crease could have easily scored and 8/8.5 (a potential dollar value of around $2000) with the majority of surface and edge damage having been caused by the folding
Makes it too easy
