You can really say, because the top tier decks we have now may be hit in march... Anyway, tier 1 (in my opinion) DinoRabbit, Agent varients, Plant synchro, chaos varients. Tier 1.5/2 (again my opinion) Dark world, piper, synchro centric, T.g varients. Tier 3 frog lancer, frog monarch, watts. Although this may change in march
