We got in a few games of sealed (in which one opens six packs of random cards and uses the contents to build a deck), as well as draft (in which many more packs are presented to the player, who chooses one card out of each pack)
That ability affects all Robots you control, not only the tokens created by the last ability
Even if your opponents arent drawing extra cards in a turn, spending three mana to draw three cards every turn cycle is incredibly powerful
If we're going to spend time flipping through our collections, saving pennies to order the cards we need, finding the exact alt-art version of our Commander, choosing the correct color of sleeves, and organizing a night with multiple people in the same place to play a game, it's worth more than a single calculation to figure out how much mana we need, and how much ramp we should run
it also works well as a self-contained creature
