In regards to the Baloths vs Avenger, the downside of both of these is that they are powerful enough outside of the landfall deck to get snagged by other random decks. So you aren't really able to target the deck that you want. The Woodcrasher is probably a safer bet to reach your goal.
Do you want a turn 5 enabler?
I didn't think of framing the problem this way, thanks for the insight.
Both of these decks could use the turn 5 enabler since Hogaak and Uro are thirsty avatar/titan people. However, I would rather have the early GY filling card.
Which leads me to Velrun's idea.
I could very well see your cube running both of them if you can find the room.
Another piece of insight I didn't consider at all for whatever reason. I can find a way to run the Cavalier for sure.
What I am now considering is if I wouldn't be better served with a GY payoff (like Titania, Protector of Argoth) since green has a lot of enablers already.
The green GY payoff cards I run are:
Tarmogoyf, Life from the Loam, Honored Hydra, Hogaak, Arisen Necropolis, Uro, Titan of Nature's Wrath and Wrenn and Six.
Are there some obvious ones I am missing?
