I've not seen these before. I'll think they'll come in handy for the next time we play. Very cool.
(unless you're super anal).
Speaking of which... some very minor typo corrections
Phase 5 Mythos
third box down on left edge
monsters who’s dimension symbol should be "whose"
and to the right of this, Black-normal and Red-fast boxes
it’s dimension symbol shold be "its"
and Blue-Flying box
in a connect street should be "connected"
(You put all this hard work in and someone just picks you up on the smallest thing. Kinda like being a game designer.)
