I started playing Solforge about a month ago. I haven't bought any packs, I just log in, get my free shit, do three games against the computer on easy, and then some random online timed matches until I get a ticket.
I have managed to put together a Nekrium - Uterra Deck that does pretty decent now. It focuses on Tarsus Deathweavers, Nightgaunts, Uterra Creature buffs, Nekrium Removal and debuffs, and an army of Creatures that spawn things in place when they die (Death Seekers, Nerali Oozes). I don't use ether hounds or hunting packs though. Ether hounds don't seem to keep up damage wise and hunting packs never seem to trigger enough for me. Nightgaunts + Dryads boon can quickly turn into a massive headache for anyone relying on creature based removal.
The only legenday I use right now is Varna's Pact, I only have one copy though. Another fun spell is Phytobomb, again I only have one copy. If I have a deathweaver out on the field and either of those cards come up along with a group buff like ferocious roar or group meal, that produces a ragequit combo half the time.
There are plenty of decks that can still destroy me. Especially anything that has those ridiculous cards that go to level 4. But this deck has produced some pretty impressive wins against decks chock full of legendary cards. I would love to get some echo wisps, more Varna's and some Fleshfiends. Deathweavers are just a lot of fun to build around.
Overall the game is pretty simple to enjoy and jumping in to get my daily rewards takes very little time. Having no chat client just feels weird though.
