Welcome.
Burning Tower isn't a bad upgrade. You'll use it later on for sure. Just don't reset any more because you'd lose a lot. If you want to try out other Element starter decks (though I dunno why; they suck), you can use the trainer (elementsthegame.com/trainer).
Mm, a classic Golem domination deck. Its weakness is very obvious in that its offense starts with 1 HP of course, so it often packs 2-4 Phoenixes (CC-resistant) and a Fahren or two. Fire Bolts are perfect, and two-three Deflags are essential. You're right on the money there, however I can see you're spending a lot of card space on the
. I imagine you get a ton of surplus
if Golems are slow or die off. When running Immo, the deck usually runs 2 Gnomes, Earth mark and Burning Pillars. Without Immo, it usually runs Earth mark and some Fire Pends. This way you get more space for Fire cards.
