10 Most Powerful Yu-Gi-Oh Monsters (In Terms Of Attack)
3. Slifer The Sky Dragon
The second Egyptian God on this list, Slifer The Sky Dragon is arguably more reliable than Ra.
Another ? ATK Monster, Slifer's ATK depends on how many cards the player has in their hand. While this can vary quite dramatically, the fact that Slifer doesn't need to leave the player vulnerable to lose to a measly Sparks in order to get upwards of 7000 ATK means that it trumps Ra any day.
Of course, the 7000 ATK cap only applies during the opponent's move, with Slifer having a potential limitless ATK during the player's turn - provided they have a few Draw accelerators to hand.
At most times, though, Slifer's ATK will match or exceed most other Monsters on this list, making Yugi's Egyptian God the most powerful in the game.
