If you really want that strategy (novablast wurm+impervious greatwurm), you need more interaction. I guess you could take a look at green devotion strategies for vomiting him onto the battlefield, but such strategies often have a tendency to run out of gas or draw the wrong half of the deck. A more interactive strategy while running these two as a top end when you want to should be stronger. A better idea would be to run tooth and nail as a top end into your 2 wurm combo.
Alternatively, if you don't want this strategy (because it's already been done or there are already 2 card I win combos) is to run the new green tutor shared summons and just cast them as you can. This allows for stronger and grindier deck, with things like collector ouphe, kitchen finks, scavenging ooze, ramunap excavator, etc. as cards that can contribute towards winning the game/stopping your opponents from winning and keeping your options full.
Regardless of what choices you do make, I would consider replacing vernal bloom with nissa, who shakes the world as 4 mana is pretty much the same as 5 mana here, or garruk wildspeaker for the additional land untap. Helping your opponents kill your faster really seems like a bad idea!
5 is pretty much the same as 4. And not to mention Nissan untap the forest so she effectively costs 3. Just like another planeswalker that effectively costs 3 even though his mana cost is 5. I hear he sees a little bit of play in modern.
