Mono-Green-Belt Rampager Combo (Standard)

Giving an old combo some new love. Making this Mono-Green.

This has a bit more resilient (with Bristling Hydra) and can work as a normal energy deck beatdown.

But of course, in a dream world, Turn 4 Kill!
Turn 1: Land + Llanowar Elves
Turn 2: Land + Servant of Conduit
Turn 3: Land + Paradox Engine
Turn 4: Greenbelt Rampager = infinite mana + infinite cast

So what do we do with infinite mana + infinite cast? Choose your weapon below:
1) Walking Ballista = Death Star = Opponent Dead
2) Rhonas's Monument = Infinite Pump + Untap Mana Dork + Attack = Opponent Dead
3) Lifecrafter's Bestiary = Infinite Draw + find the above = Opponent Dead

MVP of the deck: Lifecrafter's Bestiary. The combos are all 4 pieces or more and involve resolving a 5 mana artifact. Luckily with a Bestiary out it's virtually impossible to run out of gas. The scry every turn is also invaluable.

Mana Ramp in Llanowar Elves, Servant of Conduit and Rishkar, Peema Renegade (note that cards like longtusk cub, bristling hydra and walking ballista can put counters on their own so can produce mana with Rishkar).

Walking Ballista is an all round player in being a combo piece, artifact, creature, removal.

Longtusk Cub is an energy sink that can grow huge quickly if left unchecked. And the main combo piece itself Greenbelt Rampager can be a beatstick on its own.

Maindecking Aethersphere Harvester for lifelink against aggro deck and also to block problematic flyers such as glorybringer, heart of kiran, rekindling phoenix. Sometimes, evasion is key to hit the last points of damage (without combo).

Sideboard:
More Aethersphere Harvester. Hope of Ghirapur to attack and sac the turn we want to combo off. Heroic Intervention & Blossoming Defense to protect our pieces. We can board out some of the combo pieces to be aggressive with Verdurous Gearhulk. Prey Upon if we need much needed 'removal' against certain creature decks. Naturalize and Thrashing Brontodon for artifact and enchanment removal.
