Small World
Sauravis allows you to turn any monster in your hand into any other monster in your deck. This allows you to exchange combo pieces as required, exchange duplicates, or in a pinch, allows you to exchange a Dragoon material for any other monster.
Red-Eyes Black Dragon and Eva are the only real outliers, but for REBD, you can reveal Idaten to add any Drytron monster you need, and for Eva, you can banish Draconids.
In addition, Sauravis can be used to negate Infinite Impermanence, which is the bane of any hand with Triple Tactics Talent.
This can also be used to:
- Add ANY monster card to your hand (except Red-Eyes Black Dragon) using Sauravis as the second target.
- Swap a Machine (aka. Drytron) for another. For example: Delta into Alpha.
- Swap a Fairy for another. For example: Orange Light into Diviner. This is handy for adding Orange Light if you already have full Drytron combo.
- Swap Sauravis for any other monster. Useful for keeping in your hand for protection, then turning into a Fairy for an Ultimateness negate.
