Each player draws X cards, where X is the total amount of mana paid this way
To determine the total cost of a spell, start with the mana cost or alternative cost you're paying, add any cost increases (such as the commander tax), then apply any cost reductions (such as that of Dargo's first ability)
This order appears to have changed, causing the rosette pattern to appear blurry or cross-hatched as other colors are layered above it
When a player wants a specific card or card type, the chances of drawing that card diminish as the deck size increases
As if that wasnt enough, the equipped creature also has an ability that lets you steal sacrificed nontoken permanents unless they pay three life
I would strongly bias myself towards Mardu in any Dark-Dwellers deck
