I'm new to magic, i've been trying to make some decks and i think this seems the most promising out of all of them. I'm very open to suggestions, please have a great day.

Artifact — Equipment
Equipped creature gets +1/-1.
Whenever equipped creature dies, draw two cards.

The mind is a beautiful bounty encased in an annoying bone container.
analog narwhal
around 35-38 lands would be best here

Thank you for the advice!!
I ll have a look into land options ^^

A fun land option you might want to include would be [[drannith ruins]] as an extra little means of +1/+1 counters sometimes. Additionally [[hardened scales]] would be nice for more counters, [[silkguard]] for protection as needed, [[loam dweller]] for more ramp w/ your spirits, [[elder pine of jukai]] to get more lands, [[carven caryatid]] as a blocker and cheap spirit that cantrips, [[blossom prancer]] for card advantage on a dude, [[strangleroot geist]] to be saced for Sekki, [[realmwalker]] as a spirit & some card advantage, [[masked vandal]] for removal that plays with the graveyard, [[skalla wolf]] for more card advantage on a spirit, and finally [[iname, life aspect]] as more a kinda janky tutor effect. any and all of these can be used or discarded, just my own thoughts.

Thank you so much !
I ll have a look at all of them, i've not heard of these before

Does evolving door work in a monocolered deck? It says "exactly that many colors + one." So that may be an easy swap
2022-04-29: Evolving Door's ability instructs you to count the number of colors, but it doesn't track what those colors were. For example, if you sacrifice a creature that is green and no other colors, you'll search for any creature card that is exactly two colors, even if the card you search for isn't green.
It doesn't work in your deck.
viscid minnow

It does if you sac a colorless creature, for example the spirits his commander creates

That's actually epic. I'm so dumb.
