Rooftop Percher
The graveyard-hate creature that also gains you life is a well-worn template, and this one wears the standard clothes: a body, evasion, an enters-the-battlefield trigger that exiles two cards and pads your total by three. What sets the axis is the changeling line stapled on top. A five-mana 3/3 flier is unremarkable as a rate, but being every creature type means the same card that dents an opponent's graveyard also feeds whatever tribal shell fielded it, counting as a Bird, a Goblin, a Merfolk, and everything else the moment it lands. That dual identity is the point: the exile clause is incidental value, the type-line is the reason the card exists. Bodies like this let tribal decks fold graveyard interaction into their creature base without diluting their counts, since a disruptive creature that also triggers your anthem effects and lord bonuses costs the deck nothing on the tribe axis. The "up to two target cards" wording keeps it live in a hate-free game (you can point it at nothing and still take the three life and the flier), which is the small design courtesy that keeps it a useful creature even when there's nothing to hit. Flying is the finishing touch that lets the incidental disruption also close games in the air.
