Always nice when you try to be helpful and get downvoted
I can understand the sentiment though, as the advice here wasn't that good.
Talisman of Impulse is a very good addition. Unlike the
Farseek,
Rampant Growth, and
Sakura-Tribe Elder you suggested, both Talisman and
Arcane Signet can be used for mana immediately. Because of the generic mana cost they can get you both of your colours, even if you kept a hand without any green sources. You can also do a very strong turn 1 play of land >
Sol Ring > Talisman > something else.
The possibility of a
Vandalblast should not affect your choices of cards in a primarily creature-based deck, as it's barely going to affect you anyway. Besides, I've rarely seen it get overloaded. It's just an overrated removal spell.
35 lands is a good number for a green deck. As you (MajordomoTom) get comfortable playing the deck you may even reduce that number (
Temple of the False God should be replaced immediately though). You will want to increase your ramp package though. I count 10 ramp pieces, which isn't bad, but you'll want 3 to 5 more. I'm personally a fan of 1-cost dorks like
Elvish Mystic,
LLanowar Elves, and
Fyndhorn Elves. Playing 1 of these on turn 1 is a very strong opening move, as it puts you at 3 mana on turn 2, while everyone else is at 2. There is also
Birds of Paradise (costs a fair bit of money) and
Orcish Lumberjack (high risk), but I recommend these less.
Goblin Anarchomancer is also a good choice.
I would keep
Tibalt's Trickery, as it's a good protection spell. Still, more interaction wouldn't be a bad thing.
