I had misread Frontier Siege as "adds 2 green mana to your mana pool each turn". Yesterday, I found it adds 2 Green every main phases, that's 4 mana in two main phases a turn, that's crazily good. And its "Dragon" option is good for turning flying creatures into removals. I started to build around it. The first thing I considered is putting it into a ramp deck. We can have  Genesis Hydra ,  Polukranos, World Eater ,  Ugin, the Spirit Dragon  in the deck. To get the best outcome, we may add more ramp cards like  Voyaging Satyr ,  Sylvan Caryatid ,  Elvish Mystic ,  Nykthos, Shrine to Nyx . In the end, we will get a deck close to the Green Devotion in Grand Prix Seville 2015 top 8. On top of that, I think giving 2 Green mana every main phase is good for Morph , Manifest and some activated abilities because these activation don't require you to pay all the mana cost at once. Maybe, it can synergize with  Temur War Shaman ...

After some testing, I got a different view of what the better cards are. Whisperwood Elemental was first considered a value adding card, but in GR decks, it's too slow to turn the game around. When I have 5 mana ready, I probably need to make monstrous World Eater or cast Stormbreath to race my opponent. Whisperwood is a defensive card rather than a card dealing huge damage. However in this speedy Standard, it 's a bit off beat. I hope Abazan midrange uses it as a finisher later. Something similar happened to Shaman of the Great Hunt. I found it difficult to use its drawing ability in late game. Still, it's a strong card for adding up potential damage if I have flying attackers. Occasionally, when the blockers are cleared, it even does huge damages and finishes the game quickly. Even Yasova Dragonclaw is not as deadly as I expected. Most of the time, I couldn't find worthy targets to take control at the expense of paying 1RR, which means tap out for one turn in earl...
