So basically, no, I cannot attack with them at the same time. I don't see, though, how I can't sacrifice the old one or activate haste on a new one that I've just cast at the beginning of my turn before combat. I would be bringing in a new Drana at the beginning of a turn where there was already one Drana established on the battlefield. Couldn't I just use
Indulgent Aristocrat's ability to pay the mana cost and sacrifice the old Drana in response to the new one being played? The new one would then gain the +1+1 counters from the
Indulgent Aristocrat sacrifice and if I discarded a card from my hand I could give it another +1+1 and haste from Olivia. Board state would have changed and the state-based effect would no longer be in effect. Then I could still attack with the new Drana since all of this would happen during the first main phase.
Of course I could always sacrifice the first Drana sometime before I play the new one and avoid all of that entirely.
I didn't say anything about playing a new legendary at instant speed or trying to activate haste post declaration as an attacker, I know that's not legal.
@G. Moto they are doing pretty well. I still don't win a whole lot, but I'm slowly purchasing and improving the deck so I haven't expected quick results. They seem to
catch people off guard. Recycling cards is what I'm after, I'm trying to make sure that my discards aren't wasted efforts.
