Drana and Linvala + Kormus Bell + Urborg, Tomb of Yawgmoth

Drana and Linvala

Kormus Bell

Urborg, Tomb of Yawgmoth

How it works

1. Urborg and Kormus Bell cause all lands to be 1/1 creatures that are also Swamps in addition to their other types.
2. Because Drana and Linvala prevents your opponents from activating abilities of creatures they control, your opponents cannot activate abilities of lands or creatures they control.
