I made a list of the good bronze/silver cards to draft take two for each class., and from what I can see Dragon is the best, and Haven is the worst. Dragon will dominate take two, not by Orcas, as those are defensive options. It's Vastwing Dragons. Intimidate is very hard to answer in take two, and Dragon has like 4 bronze/silver cards that generate Vastwing Dragon. Also, Dragon has the best low rarity board clear at just bronze rarity 6pp for 5 damage AoE. And lastly, Dragon has the best distributiion of low cost and high cost low rarity cards. Portal, for example, has a lot of good low cost cards, but very little at the high end, and struggles with board clear. The 2 that surprised me the most were Rune and Forest, they have a lot more good cards for take two than you'd think. Sword is hard carried by golds, and will live and die by whether they get Gildaria and Amalia. If they get multiple of each they're tier 0, if they get none, they're tier 3, so prepare to rage at getting high rolled by swordjeets.
