Lyra Ironscale, Kin to Dragons

First strike
Whenever Lyra attacks, create a 4/4 red Dragon
creature token with flying that's tapped and
attacking. Exile that token at end of combat.
Whenever Lyra or another Dragon you control
deals combat damage to a player or planeswalker,
add {r}. Spend this mana only to cast Dragon
spells. Until end of turn, you don't lose this mana
as steps and phases end.
