Senri Shiki

If Senri is played from GY, activate this* effect immediately. Otherwise, roll a d6:
1-2: +2 against LIGHTNING and SKY, -1 against Girls.
3-5: Send a card from the hand to the GY, Senri gains that much power.
*6: Switch the opponent's played card with a random card in their hand; the card just played gets -2.
If Senri is played from the GY, return him to the bottom of the GY face-down after battle.
