Remember that you still have to follow timing restrictions, so for example, if your opponent plays a Doomskar, you aren’t able to replay the Flameskull in your opponent’s turn. Much like Anax, Hardened in the Forge, it won’t be easy for your opponent to deal with Flameskull with a single removal spell since you’ll be able to use its rejuvenation ability and recast your Skeleton whenever you get the choice. Flameskull is a powerful mythic rare from Adventures in the Forgotten Realms that’s an evasive threat that’s also hard to kill, and it fits perfectly into Mono-Red Aggro in Standard.
