If you really want the parasites, there are 2 options: 1) make this deck a fully-fledged

duo. With the other option, you need to make sure that you understand pendulums.
In a lot of mono decks, I'm sure you've seen people split their pendulums and pillars in half. This is because their mark is the same as all the other pillars they're using. what I suggest to you is to change your mark to darkness and add death pendulums, because you honestly don't need it early game.
Devourers, in a sense, act as living pillars themselves, which lowers your need for
![Darkness :darkness](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/darkness18x18.png)
even further, but you need some immediately at the start to get them out. I would suggest taking at least 3 of the darkness pendulums out for dragons.
The deck I'm thinking about is:
Mark of Darkness
5x

pillar/pendulum
5x devourer
4x parasite
2x steal
2x nightfall
3x

dragon
6x vampire
3x
![Death :death](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/death18x18.png)
pendulum
I didn't test this, but that's what I just made up off the top of my head.
