The model does not seem to get told what the cards actually do, it's just trying to guess.

Probably less of a problem for Legacy, but it isn't even told what format it's playing. So I expect it's easy to get the bots to do far better than this by giving them more information.

Let me analyze this opening hand:

*Hand analysis:* - 3 lands (Riverpyre Verge, Steam Vents, Willowrush Verge) - dual lands which is good - Monument to Endurance ({3}) - a 3-drop - Accumulate Wisdom ({1}{U}) - 2-drop, likely a blue advantage engine - Boomerang Basics ({U}) - 1-drop blue spell - Gran-Gran ({U}) - 1-drop blue creature (1/2)

This is actually a reasonable hand. I have: - 3 lands giving me mana access (with color fixing) - A 1-drop (Gran-Gran or Boomerang Basics to choose from) - A 2-drop (Accumulate Wisdom) - A 3-drop (Monument to Endurance)

The curve is solid. I have some interactive blue play with Boomerang Basics and early board presence with Gran-Gran. The mana base supports blue well with all three lands. This is keep-able — while not spectacular, it's a functional opening hand.
