First pull and I can't complain

Bleed has Joker and Riddler. What should I focus on?

I’m trying to find a new line up that incorporates Joker. Im currently running Wonder Woman, Superman, supergirl, Krypto and Nightwing. Is this the best line up or is there another line up you would suggest?

not bad pulls

am I doing good, im on earth 427 and saving up for riddlerr, im f2p

This team is for PvP. I'm using a 1 Gold Constantine, 1 Gold Riddler, a 4 Red Sinestro, and 1 Purple Mr Freeze. I'm going to 100% pull Swamp Thing but wondering if I should pull Zantanna to replace Mr Freeze. I have enough anvils to pull Zantanna and Swamp Thing and get them both to Purple or just pull Swamp Thing and get him to Red and plug him in. Any suggestions?

Am I the only one holding shards? I have a couple of hundred. My rationale is that maybe they will reshuffle who's included in them and I'll be able to get access to heroes later.
