Don’t worry about the score, I was using this team way back on that account when it was about a week old. I had them at level 10 at the time, with my tyri at just enough magic to destroy 8 gems when I first started using it (I believe level 12?) and with no traits on anybody. The team should be PvP viable at the low end, maybe 1 or 2 trophy matches, mostly because even if they have superior stats, they are generally poorly constructed in terms of mana flow.
Titan is good at this point because it is also really easy to set up. You get 4 attack for having just the first talent unlocked and it has good defensive stats, and you don’t need traits (yet). Titan is a staple class for events later, particularly the level 40 barrier talent and the traits, so it is worth leveling.
Dragonguard should be ok with just Exemplar for PvP for a good skull bash. The traits also help but aren’t strictly necessary here (yet). I have a team specifically for that, early game, that also works well - :
Dragonguard (with a weapon limited to yellow and/or red)
(any either dragon’s claw/dragon troop, or wight)
Banner set to favor gathering mana for Dragotaur. You can ping Dragotaur and Rogue back and forth occasionally while fishing for skulls while the hero gets lots of skull damage. Dragonian Monk in the last slot can make it a bit safer but slower, baby dragon/visk covers red but poorly, dragon eggs gives you a summon but you shouldn’t want to use this, etc. One of my earliest dungeon-viable teams. Works better in 2 trophy PvP than the other one probably, since it has sustain in the form of Dragotaur’s armor buff.
If this doesn’t work, you can use the hero with any weapon that doesn’t mana block, ranger, alchemist, and banshee. Or any combination of troops that can chain mana to ranger with the hero not blocking them. Hero’s spell sucks at this point, so you want them covering a color that isn’t used by the team much, but the stat wall and high skull damage are nice. Ranger’s damage output drops off significantly past a certain point, but its a good way to deliver fast damage early on.
For three trophy teams, you’ll need something that can keep the turn while dealing significant amounts of damage. Double converters (Forest Guardian, Divine Ishbaala, Wrath, Qilin, etc) and self loopers (Yao Guai) are a good way to do this if you can set them up, or just overwhelming brute force if they don’t have the stats to withstand it yet (The Dragon Soul). You can loop them to death with low rarity setups, or use cheese like bulette, but this generally takes a really long time to the point you are better off sticking to 2 trophy.
