Quote from TearingEons »So with Zegana at rare, that could mean the mythic legend is the new guildmaster. There is an art for the booster packs featuring an elf that holds not just a vial with the Simic symbol, but she also holds a trident. The trident looks exactly like the one Zegana sported in her RtR art. So maybe Zegana stepped down or there was a vote of no confidence or a take over. Either way, my bet is that it'll be that elf that's the guildmaster now.
Edit: found and attached the art
Quote from RedGauntlet »I hope is not that elf woman. So boring looking. Come on, where are the freaks and mutants from Simic? Instead we are getting another Izoni and Etrata character.
Quote from soramaro »The Simic are a scientific community, so it'd be very believeable if their leaders changed rather regularly. Leader positions involve a lot of paperwork and take up a lot of time one could use for research, so the speakers probably rotate and take sabbaticals with varying lengths.
I bet that either Combine Guildmage or the color-heavy Simic 4-drop will give out, redistribute or remove +1/+1 counters for some minor effect.
Someone on Twitter made a good point: the trident the character on the booster pack is holding is the same as the one from Prime Speaker Zegana
