Well I think I will give Kaijudo another shot you might want to check it out as well Ryu, we could probably play together and they have RL cards as well.Rise of Mythos lets you summon cards based on their timer, so if its 6 you can summon them in 6 turns which makes rush decks aka 1-2 timer cards popular. unlike swordgirls there are alot of creatures male/female available and spell cards to deal damage to a target creature or enemy player, increase attack power, defense etc. (only archer has the hero damaging spells but its pretty rare to obtain) the card illustrations and ingame sprite is dashing!!
there are also other titles Kings and Legends which was the first name, it's like another publisher renaming it, and another one is Ancient Summoners same game but ancient is the newest title not sure which has the most players though

Kingdoms CCG - this game has fine card illustrations but at first i thought it looked ugly but as you progress through the game the gameplay becomes interesting and the later cards look rather nice, like yugioh it has spell cards, equip cards, field spell cards but no tributes it uses a mana system where you replenish 2 mana every turn, it stacks so in 3 turns you get 6 mana and can summon a 6 mana use monster or use a spell worth that much mana (or use less and save mana etc)
the hero also has 3 different spells that damages player/hero, increases your creature's attack power etc. the campaigns are pretty nice. im currently playing this right now - unlike some popular card games this game is linked with every other publishers like facebook/kongregate etc but i suggest playing on kongregate for free 35 kreds
