You can drop in Golos and a few 5-color lands into a random deck and get all the ramp and card advantage you would ever want from a commander, with no worries about your mana base
One of the actions you can perform is "inking" a card from your hand
Whenever an opponent attacks you with two or more creatures, draws their second card each turn, or casts their second spell each turn, you draw a card
War Room This colorless land arrives untapped, can be tapped with three mana to swap life for a card of your color identity
Wizard Class takes some time to level up, but once you get Level 3, youll be able to add +1/+1 counters to a creature you control whenever you draw a card
Even without treasure, the ability to pump something +2/+0 would feel pretty good, but if you can give that thing death touch, thats when things will get really interesting
