Praxis Sentinel

Praxis features a few dual-colored strong Sentinels such as Powercell, Arcanum's True Heart, Arcanum Monitor, Monolith Guardian and Goldplate Goliath as well as the spell Opum's Technique.

The Sentinels are quite potent but expansive. I added each 4 Seek Power and Power Stone next to each 3 Coretap Maximizer and Powercell, but I found only 8 attachments are insufficient to reliably enable Monolith Guardian and Coretap Maximizer. This needs some refinement.

There are 9 removal effects from Purify, Opum's Technique, Laser Blast and 3 anti-flyer cards Swirl the Sands, Sandstorm Titan and Sandbinder Sentinel.

Overall, the included sentinels might need some replacements, e.g. the high-cost Pillar of Amar and Goldplate Goliath are difficult to get out and benefit from.
