@rogerandover, thanks for the feedback. I'm not a competitive player either; this deck started as a thought exercise.
I agree that
Kumano, Master Yamabushi and
Walking Ballista are better than
Goblin Dynamo once I have infinite mana, but the
2:1 or
4:1 rate of damage output gets quickly outpaced if I haven't gone infinite, but have 30+ mana (which is somewhat common). They each interact with my conditional tutors somewhat differently (eg. hulk vs recruiter) but are probably worth testing. I added
Soul of Shandalar to have a repeatable damage source that hit the overlap between hulk and
Fierce Empath so I may test
Walking Ballista replacing
Goblin Dynamo.
I think that there are 5 more 1 CMC manadorks that I could play, including
Orcish Lumberjack. There are also three 1 CMC creatures that could play an extra land on turn 1. I'm leaning towards trying fewer lands and dropping
Blossom Dryad and
Wood Elves and the bad fetches for the mana dorks. I don't think that I could do both because the risk of not having lands to play would be higher.
Vizier of the Menagerie should be played for more cards. At the least, it could replace
Garruk's Horde. Honestly, I should also play
Prowling Serpopard here too; I forget about Amhonket block a lot. I'm not sure about tireless tracker, I play it in another deck and am usually not impressed at it's speed.
Zealous Conscripts is one of those 2 card combos that I usually avoid because it's too straightforward, so I didn't even think about it. That's a good addition here due to the unrestrained nature of this build. Probably drop
Zhur-Taa Ancient for this effect.
Maze of Ith has two possible combos here, that's probably worth the slot despite being dead otherwise.
I've never seen that
Stone-Seeder Hierophant +
Thawing Glaciers engine before, that's definitely getting a slot. Either get lands equal to the mana I can make or all of them with
Lotus Cobra.
I'd built this deck around the same time as a
Wrenn and Six +
Harrow Oathbreaker deck that ramped to Valakut, which uses the
Thespian's Stage +
Vesuva mentioned. I should have already included that effect. Of the two, I'm more likely to use the stage because it enters untapped. Honestly, Valakut was added as another wincon with infinite landfall via
Temur Sabertooth +
Quirion Ranger +
Sakura-Tribe Scout and either another mana flare or
Lotus Cobra because I was already playing those cards. This would add some extra non-infinite reach. Adding
Realm Seekers makes sense to set up more of these combos, because I usually hold back
Ulvenwald Hydra until I know which land enables a combo (or just to go for commander damage via
Kessig Wolf Run).
Genesis Hydra is great after I have infinite mana to enable a win, but more difficult to play when the deck is semi-storming and non-infinite. I would have trouble deciding on what value I should use for X here. That doesn't make it bad and the open question implies that I should test it.
