back to topic, you also asked about mixing cultures and strategies:
"If a man tries to catch two rabbits, he catches none." - Confuzius
What I exactly wanted to say is, that you should really stik with one big plan and try to eliminate weaknesses in your Deck. As example, at least one
Shotgun Enquea or another crwod control card is Staple in a Moria Swarm, as it would die to big fellowships with lots of wounding à la
Greenleaf/
Aragorn's Bow. That' the first point about mixing cultures.
another point is Gollum. He's a great Splashing culture.
DaD for Twilight Nazzies,
Stinker for Corruption,
Threatening Guide for Decks with threat manipulating,
Old Villain for cycling, and of course
CBTR grabs Gollum from discard or deck. Gollum is there as a complement for the Deck, as might be some other cards. But I don't want to get too Deck-specific. There are lots of threads about Splashing comps at the boards.
upshot:
-> mixing cultures: rather yes
-> mixing strategies: rather no, besides Splashes.
