If I were to design a card for an SHL/SMJHL based trading card game, it would be a support/item card called "rage of youth". The card would grant the user a choice of two abilities, either a +5 attack on the turn it is used, or +1 attack which becomes +4 attack after three turns in play and is permanent. These would be the effects because it represents the situation of the Rage right now. While we are a young team and can show glimpses of greatness in individual games (represented by the +5 attack), usually we aren't the strongest team at the moment (+1 attack). However come another season or two, we will be much stronger for a long time, hence the permanent +4 attack. This card would also be good for the game as the user can either decide to be in win-now or future planning mode.
