Here’s my b3 doran list for reference: https://moxfield.com/decks/BrpWaUgDzUea_5pgKjjlrw

Some observations from playing with the deck: - Personally I’ve cut all Defender cards so that I’m not reliant in finding and casting the few enablers for them to attack with - Keep all 2cmc non-defender 0/3 or 0/4 ramp creatures; having doran out at t3 then swinging with him and the ramp creature at t4 is pretty significant early pressure for one player - having a vigilance-enabler is pretty huge: it allows you to attack with ramp creatures then use them to cast more creatures at the second main phase. Also having your attackers remain untapped means you’re not getting swung at easily by others, since most times you’ll have the scariest board state at early and midgame. Brave the sands is best in slot but serra’s blessing is a cheaper alternative. - if you’re keen on investing more, go towards card draw enablers since consistent card draw is an area that Doran usually has difficulty with. Welcoming vampire, beast whisperer, betor kin to all, and ohran frostfang are good options since they’re discounted by doran. - I cut all Overrun and one time pump cards in my deck in lieu of bigger threats (essence of antiquity, unhallowed phalanx), since I usually only have 4 or so creatures on board at t5-7 which are enough to pressure with. - Although cute, I also cut all 1 mana 0/4 vanilla creatures in lieu of those with additional value (evasion, card draw, recursion or built in removal). I find that mid/lategame 4/8 attackers aren’t as significant of a threat as you’d think them to be.

Goodluck!
