This is a mono green devotion/ ‘ramp into huge threats’ deck.
More mana symbols in a cards cost is usually viewed as general disadvantage, because it is difficult to splash for it. Therefore, cards that have more mana symbols in their cost (as opposed to generic mana ) also have an upside, to balance the card. This deck is meant to sort of abuse the value of many- symbol cards, and turn the potential disadvantage of the nonsplashability into an edge over your opponents.
If you have Gigantosaurus, in your opening hand, you should be able to cast it on turn 3 fairly frequently, due to the fact that 12/60 cards in this deck are ramp elves, so every card you get is a 1/5 chance of being an elf. So, it isn’t too far fetched to think that you could have a massive 10/10 T3. That is value! With some luck (getting three elves and three lands by turn 3), you could even get a Terra Stomper out.
Use your value guys (Giganto, Stomper, Vorapede, Leatherback), and use their devotion for more advantage, and win!
