it's a pretty simple budget deck, almost every card in it also has to buff Halana and Alena's toughness one way or the other.

That keeps the deck really consistent, it wins by making Halana and Alena huge, then they make something else huge to do huge damage.

It's one of the first decks i made, i just cleaned it up last night because i had removed a couple staples from it over time (e.g. kenrith's transformation) to make other decks.

Now that i am looking at it, i think i can make it a bit smarter, like instead of spells to remove artifacts i should use creatures like manglehorn, because creatures can get buffed up by halana and alena in a pinch.

Any smart or clever cards I can include? It's mostly struggling with card draw effects and protection from boardwipes.

rancor is a cheap and effective buff, and you pretty much can't go wrong with Rishkars Expertise and Return of the Wildspeaker.

Some scalable cards like [[tyvar stand]] or [[primal might]] would be nice

Target creature you control gets +X/+X and gains hexproof and indestructible until end of turn. (A creature with hexproof and indestructible can't be the target of spells or abilities your opponents control. Damage and effects that say "destroy" don't destroy it.)
