Ummm, tier 1 is UWx Control, MBC, Mono U and Burn. Flamespeaker is fine in that meta and excellent against lower tier decks that you WILL face at a larger event. Sure, it's bad if your approach is to YOLO everyone, but that not the cards fault, it's just not going to synergise with your strategy very well. If you like playing incremental grindy games, you'll like Flamespeaker.
Can't argue with that, its also the reason why I'm overly bias with Stoke the Flames.
I disagree with Control and MBC but I guess if you have a way too grind out all the removals and jaces before hand (with maybe YP$ and Phoenixes) then its great, though alone it doesn't stand very well against them (this is reflected in the overall burn
finishes online as well, since the card is almost non-existent with decks which finish).
