I think Blaziken is good. Non GX + GX have synergy, they both share the same evolutionary line and 3 cost for 210dmg is worth it, and non GX's 3energy for 90/ 20 each benched pokemon seems nice too, but only when exilir + strong energy rotates. Until that, buzzwole will be the only good deck.
Sceptile is autowin against any ultrabeast decks, specially without Garbotoxin post rotation. UBs are everywhere, and are, 99% of time,, the main attackers, so of course sceptile will be good (as long as UBs are Tier 1).
