Depends. You aiming to do well in raid events, or battle royale?

If you're looking at raid events, go for raid cards and high efficiency cards. Your frontline should consist of 1-2 raid cards, followed by three with a high attack/power ratio. Good high efficiency cards include Sacred Mountain Hunter, Jotun and Frosty Girl, Puppeteer Satanachia, Roaring Nidhogg, all of which should be reasonably easy to obtain (especially hunter). For more, use this link. Since only raid skills work, having good skills is irrelevant for this event. Element boosts also don't take effect so feel free to use non-fire cards.

If you're looking to build a great front line for battle royale or general battling, find cards with good skills first and foremost. Skills are the most important in battle (next to a strong backline). For this reason, find cheap rare or ultra rare cards with a good skill. Grim reaper isn't a bad card to have for fire, considering it's EX has a large boost to fire attack.

Considering what you already have in your lineup, I would probably drop eleanora and rhea for regular battles, since their skills are useless outside of events. An atar or daemon would be better suited. If you want to get good front line ultras, than barb or pupp would serve better than urd or maat, even if barb and pupp are more expensive. Zera is reasonably priced, considering her ability. Noreen and Aither aren't bad as affordable options either, since they both give a large boost to attack when evolved (even if they aren't your element). I would check Best Deck for more advice on front lines.

While you're at it, don't forget to pump up your back line. Honestly, when I started all I did was stack my back line. For months after, despite only having atar, daemon, and zairic as my front line main stays, I still managed to beat decks with multiple ultra rares simply because of my back line and high attack power.
