Rules when discarding cads from the hand to the Graveyard (discard pile).
You HAVE to send 1 (or 2/Sometimes 3-Graceful Charity/Transendent Wings) card/s
Magic Cards:
Such as:
Graceful Charity
Monster Reincarnation
Special Hurricane
Transcendent Wings (works with Winged Kuriboh only)
Monsters:
Dark Paladin (My Favorite fusion (I use 3 of this one)
Sinister Serpent
Armed Dragon's: Lv's 3, 5, 7 & 10 (I only use 5 & 7)
Yeah, it's kinda what they said. If you discard a monster to the graveyard, it will have to vary on the card effect. Such cards like Trade In or Foolish Burial are an example.
