Tygris: just being able to create 0/0 tokens for Taigas sake (farewell sanity of Orisolve), and maybe after each use base stat for token increases by 1/1 (not being Taiga abusable T_T)
Ac Ascended: each AC that is not dual faction takes and enchants mechanic common to faction or evolves to dragon by not so distant mechanic. AC Ascended doesn't feel like evolving type and could do champion related relief, when deployed champion restriction is increased to 2 (or be more aggressive unit attacking twice fist as flying second as ground unit gaining protective buff (similar to aberion's banner) +7/7, or order vice versa. Biggest concern is to fit most of this text in to card box -_-'
Gao Han: Is champion and could also relieve champion limit or how buffing is theme both in oos and dod, double your buffs while Gao Han is in defense zone (+16/16 strength of leadership)
Aberion Champion of forge: Why would 2 oos 1fd be used over 2fd oos? If this had other things to look for other than huge morale cost, While in assault zone charge units get flying and flying units get charge. This could protect early charge units if played from command on curve, make champion swapping sol have haste and when pulled back in fear of board clear not make flying units played from hand go suicide (shikana, jubalia and cheryl late game Charlies angel's gang)
Fire starter: This guy and Tullio... I thought maybe increase power by 2-4 but its not that simple at all T_T. So effect must be more unique. If AC Fire starter would engage unit that was not deployed at the start of turn, that unit moves to assault zone and attacks after AC Fire starter
AC Hellbringer: there are variations for 2 exile sleeper/dod toxic decks so discarding (*cough, cough) calamity and making it have exile reduction of 3 on curve and removing used card from grave and deck, nope! Bad idea that sucks player interaction to its lowest it has ever been. 2 wp 1 exile Karckk is interesting. Giving 2 and 3 exile comeback in form of AC Hellbringer? Pay extra to increase discards by 2 for each resource and gain effects: 2+ discards, draw card for each discard. 4+ enemy units lose 2/0 for each discard 5+ AC Hellbringer won't transform in to dragon, he instead gains flying and spawns 25/25 unstoppable flying dragon. (Too much text T_T)
Hinekri: If Hinekri would be killed, you may instead sacrifice your unit that was infected by Hinekri.
Vasir the demon Prince: Opponent units lose morale from sacrificed units (usable in 3p verore, vorasious goliath followed by vasir?)
Die another day: While in hand cost decrease by 2 every time you take 20+ damage.
Evellee: I didn't think my favorite unit need buff o_O +2/0 for recruited units
Xi, Martyr of peace: Heal your fortress full and win game with Dugg you have earned it. Or rather after sacrifice, for rest of the game after your unit dies or is removed from game in battle field, spirit with identical stats moves to another zone and leaves at the end of turn (i have lost my imagination for this one (T^T)
Liand, The fearless: units in defense zone also get +0/4
Marina The selfless: Aleta effect returning to hand after 4th turn (very original...)
