I want to play seriously in a beginner legacy context but I would need some advice about the deck first.
Imo I think it's way too slow pasted and I'll just get crushed by aggro decks. Been playing quite alot with friend and I didn't see any major issue with it but i'd like some feedback from more experienced people.

Could you take a look at it and give me some impressions please :) ?

Sooo, at a quick glance, I have noticed that you have a few cards that are a bit unnecessary. Stormscape familiar and phyrexian altar are good cards, but I don't think that you will end up needing them. Your mana curve is already pretty low, so I doubt you will have any problems with mana. Also, your deck is significantly more white based than blue but you are keeping the same number of lands. I suggest cutting down on your blue lands, adding more white. The statistics bar can help you figure out the perfect ratio.

EDIT: some spot-removal could be handy for when you are not facing pure aggro
EDIT_2: also think about your deck in terms of win-cons or win conditions. If your main win condition is to over-aggro someone, a good mid-range deck will take you out with ease. Try building it around a specific leader type bird with the others supporting him, not just a mass of creatures.

Thanks for replying ! :D

I'll take a look about what you said. Overall would you say it's decent for casual competitive play with a little tweak ?

Yeah, for casual it will probably be fine. However, if you want to go into some tournaments, I would definitely make some small adjustments.
