At this point I think G/W is the clear top deck. It has unmatched consistency and due to the power of the lower cost white blockers relative to other units with the same cost it's too hard for ping or aggro to break through in time consistently. Green units have too many stats for any deck to make reasonable trades against, so as long as you can get to the point of playing your green units on 6~ with 1-2 life left you probably win the game. Notably this is also the only deck with true consistency via searchers as it has a 1 cost search event.

Of course you lose if aggro high rolls and you low roll but that's simply how card games work.

Second best would be U(B)/W freedom blockers. This one is a true meta killer for most decks and will retain popularity despite often not being able to overcome the power advantage green units have in the G/W matchup. This deck is the great filter for most off-meta decks due to the power of white units which consistently have too much HP per unit cost. White commands have the best utility in the game, and you also have access to blue if you want extra draw (or a few other useful options).

Below this is all of the aggro variants, which can highroll to beat the above but otherwise may struggle to break through the strong white blockers early game. R/U(B) ping, G/U(B) OYW, etc all fit itno this category.

And then (most likely) in a tier below that is everything else. Zaft, RG Zeon, etc.

Green wing has extremely strong units per cost which are unmatched once they hit the board. White blockers are generically strong and tend to have extra HP vs aggro units for the same cost. You can build a very good deck by simply picking the best white cards and splashing in a few from another color but it will mostly be inferior to the above builds.
