Budget Commander - Tribal Cycle
These affordable decks generally have three things going on:
1) tribal themes that help the decks feel functional simply by playing your creatures and engaging on the battlefield;
2) mechanical themes (e.g., milling, equipment), as indicated by the commander; and
3) combos that will rarely come together but are in there nonetheless.
All decks loosely adhere to the "Dollar General" (1DH) cost restrictions and have "high power" commanders that are a step up from casual commanders but are not necessarily going to do well against highly competitive decks.
