They can build up a nasty team quickly, but I really like including them in aristocrat decks for a consistent source of sacrifice fodder
It covers a wide range of TCG's not just Magic the Gathering
If you choose the rebound, your deck will not be shuffled
What are you going to do for the rest of the game? Omen will be an ability on certain dragon cards that essentially lets them be useful to draw other cards, and then be saved back into your deck for later once youve ramped up your mana resources: an instant ability that lets you draw an amount of cards, and then discard the card that used Omen, shuffling it back into your library
The fact that it can slot into any deck is a nice upside
We played against control three times, going 1-2, although the matchup didn't feel that bad (it really depends on how many sideboard counterspells we can draw)
