I hate how much of the word count is used to temporarily change the creature type of this - and then the card itself doesn't even use it.

The abilities are also at odds with one another - you'd need vigilance or something to both use the attack trigger and the activated ability in the same turn cycle.

If this at least had "Then untap ~ if it is a Rogue Scout", except that's a pay-offfor a still very convoluted setup.

I also don't see this as mythic. The attack trigger is less impressive than what Scavenging Ooze does, especially since it is an attack trigger. And the activated ability would be scary (beyond what I would advise) if it could fateseal, but basically milling two cards, but you don't get to mill them both is really, really unimpressive.

On the flavor-front it's also not clear why a Lorekeeper is a Rogue Scout rather than e. g. a Druid Shaman.

The card has many ideas that don't really come together for me.

Early on in this design, I forgot one key feature- this is supposed to be the green mythic for both Scouts and Citizens, not Rogues. I feel the ability does not reflect Citizens of Washikow in any way. A new design must take the place of this card.

I thought the semi-Fatesealing (Fateseal-inspired? Fateseallike?) ability felt mythic. The problem was making the creature fell green. Green can exile cards from the graveyard. We don't want a strictly better Scavenging Ooze, so I thought lifegain would be okay. The trigger was forced, when it could just have been an activated ability like Scooze though.
