you may play that card this turn mtg Count on Luck | Aetherdrift Can someone explain this card

It doesnt do much in EDH, however

Marcy: Probably one of the more interesting mana dorks, in that you get Energy, not mana, but the trade off is also that you get to buff all your creatures

Strong card flow, no one cares about life loss in Commander, and you can add loyalty counters to your other 'walkers without pulling planeswalkers and then you can add in +1/+1 counters to your stuff and counters onto Helix Pinnacle to win and then poison on foes and then also -1/-1 on their stuff

Each one has a strong questing value that forces opponents to challenge or risk falling behind, and then once challenged and/or banished, their effects activate drawing you cards, forcing opponents to discard or return a character to their hand, and more

Its safe to assume that we will witness the end of all abilities, tokens and copies of spells

While some are easy to point to and find out, others still remain due to time
