The explosion card is not funny but we always play with it, I buy it that when someone shoot at you and he/her hit the tank and it all explode.
But with 2 beer´s in my brain I came up with this houserule, when you take the explosion card shuffle your cards you play with in the turn and fly on, and/or maybe treat it as same effect as jamming "3 manuver cards".
If you get explosion as the last card in a turn choose 3 new card for the next turn and shuffle, and fly on but maybe not as you want.
If you get it on first card shuffle all three card draw two and fly on.
If you get it as second card in a turn shuffle the 2 used cards and the 3:rd and draw one of these and use it as the last card in the turn.
Just a thought I had maybe useful or not, I hope you understand.
Over and out.
