Special Summons itself from your Spell & Trap Card Zone
Treated as a Normal Monster / Treats itself as a Tuner monster
The fact it's an earth tuner makes synchro summoning Goyo Guardian so easy in any decks that uses level 4 monsters, 2800 attack at lv 6 and steals opponent's monsters is still OP as it was before Goyo had errata when it was generic synchro before only EARTH tuner restriction
There's nothing stopping you from buying more copies of the deck with RL cash. That being said, Shapesister isn't an amazing card anyway. There's plenty of ways to Special Summon a Level 2 Tuner, even currently in Duel Links.
