• Flying Thunder God. If Minato tagged him and left a Shadow Clone and a hidden FTG Kunai in the real world, its game over.
If Minato had to use Rasengan and Obito go untouchable for his entire body, Minato can teleport into his dimension, leave a Kage Bushin there and come back using the hidden FTG Kunai is the real world. Thereby he losses the advantage of Kamui.
• Deidara's Explosive Clones: - Obito can be fooled by Deidara's clones because even Sasuke was fooled, meaning Sharingan is meaningless seeing through this. If Obito sucked in a clone deidara that could mean trouble. If Deidara had to use a full blast Obito obviously would go untouchable, and Clone Deidara in the other dimension can blow up, resulting in big problems.
• Paper Bombs: - Simple but really effective. Shown by Konan.
