(Well Rabidragon is ok for cheap blue eyes decks that use Ancient Rules and Birthright but that is another matter.)
I was thinking this is ok for the Vagabond games where you start with 8k life. Set a character skill with the "Start with 1k life extra", run Supremacy Berry and Rain of Mercy and, if you have it, Solemn Wishes.
y'all are stupid. This speeds up my kaiba farm deck by a ton.
