This is my current decklist: https://www.hearthpwn.com/decks/1264789-handdruid-is-back-ft-keeper-stalladris-and

I was thinking about swapping Crystal Powers for Crystalsong Portals, because they will help you in those situations where you don't draw any of your big hand minions (or when you've played them all).

Thanks in advance! 

I think some cards don't make the most sense in the deck so I would try to work on swapping those cards.

Crystal Power just has no synergy really. Yes it is flexible and works good with Keeper Stalladris but I don't think that is worth it.

Mecharoo is a one drop to help fight for the board but I don't think is worth it either.

I feel like the cards you really are missing out on right now would be Mulchmuncher because you have a lot of treant generating cards and Ferocious Howl as it's card draw and a bit of armor gain.

Dendrologist and The Forest's Aid also could be cards to look into as it has the treant synergies.

I always included Splintergraft in this deck to double up on giants.

On the topic of giants: Consider Sea Giant as well (and Mulchmuncher as mentioned before).
