The main caveat to this is that to have them in your deck, both colors must match the colors you built your deck with
The net result is that threats like Hazoret, Kalitas, [Card]Glorybringer[/Card], and just three-drops with high toughness in general, are surprisingly difficult to bring down and can easily take over the game against an opponent who showed too much respect for [Card]Bomat Courier[/Card]
