Which one do you like better the new DC legends
Holly Granger <> Hawk, T'Charr's Chosen
Reservist
Holly Granger gets +3/+3 while both she and Dawn Granger are attacking.
And
Dawn Granger <> Dove, Terataya's ChosenReservist
[Teen Titans Icon] characters you control have flight.

OR

old school Legionares version
Dawn Granger <> Dove - Avatar of Order
Substitute
While Dawn Granger is team attacking, attackers get +1 ATK.
And
Holly Granger <> Hawk - Avatar of Chaos
Substitute
When Holly Granger comes into play, if you don't control Dawn Granger, you may search your deck for a card named Dawn Granger with version Avatar of Order, put it into your front row, and shuffle your deck.

I personnaly like the having flight with everyone useing Dawn Granger <> Dove, Terataya's Chosen and having to be able to search and get a extra charecter with Holly Granger <> Hawk - Avatar of Chaos

With 4-drop Tim Drake I like the DCL version, because you get 14 dmg from a one drop and a two drop attacking together and the flight allows you to effectively get any character on the board thats a 6 drop or less no matter where in the visible area the defender is.

The other version is nice if you need more characters on the board since your getting a one and two drop for the price of a two drop. But the stats are pretty bad on them. That one is probably better in a TT/Outsiders build to give you extra characters to feed Kimiyo and BaO.
