I'm trying to build a fun, casual Reanimator deck using Kess, Dissident Mage, but I'm having a little trouble: Moxfield Decklist

Basically the deck is pretty inconsistent and susceptible and also not very interactive. Meaning I might be lucky and reanimate a big threat turn 3-4, but it's a single threat that can be easily dealt with. And because it is a big threat, it usually is the immediate focus. While others build their board, I filter cards until I can reanimate another big threat, leaving my board pretty empty. This could be compensated with interactions, but because the deck needs enough big threats, filter/loot cards and reanimate spells, there is little space.

I run a couple of tutors to help with the consistency, but they are kind of inappropriate for the power level of the deck. So sometimes I replace them with less good draws/threats/reanimates.

I feel like my only course is to play even more impactful threats, which are expensive to get, but also increase the power level inconsistency, while making me the target, because there could be something very bad incoming at any time.

So, is there a way to keep this a casual deck, but also make it more consistent and interactive? Maybe focusing a little more on spellslinging?

Edit: In the end I came to turns with the fact that a reanimator strategy alone does not work in a 4-player game (except maybe with much stronger targets). So I build the deck a little more into the spellslinger direction, cut the Demonic Tutor and accepted that it will be a power level 6 like my other decks.
