netn10: This should probably generate an emblem or there will be memory issues. This would probably net you 5-6 cards on the same turn you play Urban Evolution so yeah, pretty good.
Flatline: Urban Evolution brings this card down to a single mana considering your first draw of the turn as well. You can even get your last mana by potentially drawing/playing an additional Island for the turn. Nice synergy!
Hemlock: Two mana 4/4. Seems pretty fun for sure.
Cardz5000: I get how this card plays with Urban Evolution, but it's not something I would play alongside it at all. You spend 9 mana and two cards for a 2/2 that doesn't even get you an immediate payoff like the sorcery you just cast would have?
Legend: Can be very powerful in the right deck, and with Urban Evolution this sets a good precedent. Is this an ideal card to play on the same turn as UE? Only if you play this card first then cast it, meaning it basically costs GU. Good card, it has potential to be very easily broken but some cards are just like that.
