For sealed and draft, the ETB tapped dual lands won't show up in the common slots in boosters, rather replacing the basic land in 5 out of every 12 packs.
Heroic Reinforcements has the incorrect casting cost.
Patient Rebuilding appears to draw its controller a card for each land card in the graveyard that had ever been milled by
Patient Rebuilding, not just milled this turn.
CPU was at 5 life with 4 creatures on the battlefield. I played
Demanding Dragon and CPU took the 5 damage and lost rather than sac a creature.
Edit: It appears the issue with
Demanding Dragon isn't with the CPU choice, but that Demanding dragon didn't offer the choice. CPU played it against me and dealt 5 damage and I wasn't given an option to sac a creature.
