Staying in theme with the mechanical monstrosities from the miniature game, the Necron Dynasties deck focuses heavily on artifact strategies and creating tons of artifact tokens
Typically, the extra cost for the Treasure tokens is worth it, as it gives you more mana flexibility later down the line
It's basically a build-your-own-combo card, but also has the very unique effect of taking on the triggered abilities of other cards, something I only recall seeing on Idris, Soul of the TARDIS
Displacer Kitten also gives you the ability to target non-land permanents like Brago and Yorion, but its flicker clause only triggers when you cast a non-creature spell
Previously only available from local game stores, every format of the expansion (excluding the gift bundle) can now be purchased from Amazon, while other retailers like Best Buy are offering a more limited selection
